One of the main arguments made in favor the of US (or non-US) Government recognizing same-sex marriage is the "equality" one - that heterosexual couples have unequal rights with same-sex couples in that the former can have their marriages recognized by the state and the latter can not, and such recognition confers rights and benefits.
The solution seemingly uniformly advocated by Gay Rights groups is to adjust the rights to the "high watermark" to achieve equality - namely, for the government to recognize same-sex couples.
Are there any notable Gay Rights groups that advocate the opposite solution (which is usually advocated by libertarian-ish crowd), of achieving equality by moving to "low watermark" - namely, having the government not recognize ANY marriage, same-sex or heterosexual - at all?
(the practical implementation of such a solution is somewhat outside the scope of the question, but the usual proposed approach is 100% contract based).
I will accept pretty much any definition of notability - someone with more than double-digits social media followers, someone whose position was covered by mainstream media or notable online news sources, general or LGBT specific, someone involved with politics or especially holding an elected office.
UPDATE - I'm fine if the group in question words their position as "we are happy with EITHER of the 2 watermarks equally", e.g. as long as they view "No government marriage" just as valid a solution as "same sex marriage recognized by the state"; although if exists I'd rather like to know of a group for whom the first is the preferred option.
