This is a pretty badly framed question, particularly in its title, but if the question centers on Che's role in the camp[s]...
No legitimate arguments can be made to defend Che's principal role in setting up Cuba's first labor camp in the Guanahacabibes region in western Cuba in 1960-1961, to confine people who had committed no crime punishable by law, revolutionary or otherwise. Che defended that initiative with his usual frankness:
[We] only send to Guanahacabibes those doubtful cases where we are not sure people should go to jail. I believe that people who should go to jail should go to jail anyway. Whether long-standing militants or whatever, they should go to jail. We send to Guanahacabibes those people who should not go to jail, people who have committed crimes against revolutionary morals, to a greater or lesser degree, along with simultaneous sanctions like being deprived of their posts, and in other cases not those sanctions, but rather to be reeducated through labor. It is hard labor, not brute labor, rather the working conditions are harsh but they are not brutal...(p.178)
Clearly, Che Guevara played a key role in inaugurating a tradition of arbitrary administrative, non-judicial detentions, later used in the UMAP camps for the confinement of dissidents and social "deviants": homosexuals, Jehovahs Witnesses, practitioners of secret Afro-Cuban religions such as Abakua, and non-political rebels. In the 80s and 90s this non-judicial, forced confinement was also applied to AIDS victims.

Even ignoring Farber's commentary, it's pretty clear from Che's own writing that putting homosexuals in that camp is not inconceivable.
A much less stark view of Guanahacabibes is given in Helen Yaffe's 2014 PhD Thesis:
Moral incentives were institutionalised in MININD through Socialist Emulation and
Voluntary Labour. [...] San Miguel de los Banos was a form of
moral award, a recuperation hotel for worn out workers, while Guanahacabibes, a
rehabilitation centre, took the form of a moral disincentive.
The Rehabilitation Centre at Uvero Quemado, in Pinar del Rio province in the east of
Cuba, was on the Guanahacabibes peninsula, the name by which the Centre became
known. There are two important characteristics about the Centre. First, only EC
directors and other ministry management personnel were sent there, not
administrators of production units, nor the production workers. Second, going to the camp was optional; those who did not accept the reprimand could reject it by leaving
MININD. Given the voluntary nature of the camp, and its political education
function, Guanahacabibes is assessed as one of the policies formulated within the
BFS which aimed to raise consciousness. It was a kind of moral disincentive.
The roots of Guanahacabibes lay in the hard labour camp set up by the Department
of Education of the Rebel Army on Cayo Largo in 1959 for soldiers under
reprimand. Guevara was involved with Cayo Largo in his capacity as head of
training for the Rebel Army. Cayo Largo is a sandy, mosquito-plagued island of 32
kilometres long, a maximum of 800 metres wide and three metres above sea level.
200-300 members of the Rebel Army were sent there instead of to prison for
undisciplined behaviour or pretty crimes. They worked on construction. Cayo Largo
was not considered safe for civilian projects because of the threat of military attack;
it is close to the Playa Giron where the Bay of Pigs invasion took place in April
After the Department of Industrialisation was set up, Guevara sent Jorge Ruiz, a
leading member of the 26 July Movement and an architect, to assess the camp. [...] Ruiz’s recommended that the camp at Cayo Largo be closed down and that inmates
either be given licence to return to the armed forces, sent to goal to finish sentences
for crimes committed, sent to school, or just released. Cayo Largo was gradually
transformed from a punishment centre into fishing centre and tourist resort, which it remains today. However, during this process, Ruiz said that Guevara got so
annoyed with the people in charge there that he wiped his hands of the issue.
Meanwhile, he sent Ruiz to find an alternative venue for a rehabilitation camp for
MININD which would have an educational function. Ruiz chose the Guanahacabibes
There was no legislation to send people to
Guanahacabibes, it was an initiative introduced by Guevara, which some of the
Revolution’s leadership did not approve. Guanahacabibes was for those who had committed administrative errors. Those
accused of criminal activity were sent to a normal criminal court. Initially, Guevara
himself determined the punishment for administrative failings, such as adjusting
inventories, carrying out unauthorised investments, ignoring MININD’s regulations
and other miscalculations which jeopardised production and planning. Then the
Administrative Disciplinary Commission (CODIAD) was set up. As Head of
Supervision, Juan Borroto was involved in the Commission. He said: ‘When Che
created the CODIAD he told us that he had made a mistake at the beginning by
taking unilateral decisions and he preferred they were made by the CODIAD.’ The
Commission’s most severe punishment for administrative errors was to recommend
someone be sent to Guanahacabibes for between one month and one year.
When a companero was sent to Guanahacabibes they made the journey alone. This
involved several buses, trucks and a long walk; a journey of 350 kilometres which
took 5 to 6 hours. All of which reinforced the voluntary nature of the reprimand.
Yaffe then quotes pretty much the same material from Che as Farber (see first quote), which Che apparently said in January 1962.
So clearly there are fairly different interpretations on the nature of the Guanahacabibes camp even in fairly contemporary works. But it does seem from the more detailed account that it was "prison lite" for nomenclaturists. It's not inconceivable that some were sent there for homosexuality, but most were apparently for other issues (having made administrative errors etc.)
There is a bit more to be said about Che and homosexuality, from the angle of Che's (pretty deep apparently) interest in psychology. Due to this interest, Che set up various commissions that used psychological testing both on prisoners and on personnel. Yaffe retells an account by Angel Arcos Bergnes who made a personal intervention to Che for the latter to overlook a psychological test predicting that a friend of Arcos, who was a candidate for an EC director job, was a "repressed homosexual". Two months later, the candidate was spotted performing a homosexual act in a cinema. This apparently reinforced Che's trust in psychological testing. Alas nothing is said about what happened to the candidate (Arcos's friend) in the aftermath; nor is his name given. But the fact they were looking/testing for "repressed homosexuals" in order to [at least] not hire them [at this stage] does probably foretell the more drastic measures later taken against homosexuals (UMAP camps, etc.)
