I can't find a full transcript, but the part about "whichever kind" was about opposition, not about ethnicity, as WaPo contextualized it.
Some critics have argued that banning all Russians would unfairly impact those who have left their country because they disagree with President Vladimir Putin’s government and his decision to attack Ukraine.
Zelensky said such distinctions don’t matter: “Whichever kind of Russian … make them go to Russia.”
“They’ll understand then,” he said. “They’ll say, ‘This [war] has nothing to do with us. The whole population can’t be held responsible, can it?’ It can. The population picked this government and they’re not fighting it, not arguing with it, not shouting at it.”
“Don’t you want this isolation?” Zelensky added, speaking as if he were addressing Russians directly. “You’re telling the whole world that it must live by your rules. Then go and live there. This is the only way to influence Putin.”
Zelenskyy is clearly upset that Russians (inside Russia) aren't protesting more. He might have a point in the sense that after massive crackdowns in March, protests in Russia are rather muted nowadays. If you want my 2 cents stating the obvious, the West is rather unlikely to give up its asylum policies for opponents who do flee. On the other hand, tourist visas for run-of-the-mill Russian citizens could be more open for Western sanctions. Whether that would be effective in ratcheting up any sort of pressure on Putin... remains to be seen.
For what's worth it, a few days later, in another interview
Zelensky said his proposal did not apply to Russians who needed help for risking their freedom or their lives by resisting Kremlin leader Vladimir Putin’s policies.
So he did seem to realize what I said in my previous para.
It seems a bunch of Eastern European countries (Poland, Latvia, Estonia, the Czech Republic) have indeed stopped issuing tourist visas to Russians. (Confusingly, Finland has issued a lot of tourists visas to Russians recently, but they are also calling for a EU-wide restriction.) On the other hand, Germany is strongly opposed to that measure, and since Schengen visas are valid alongside the whole EU border that has created frictions between said Eastern countries, which are the remaining [direct] entry points for Russians into Schengen, since air travel from Russia was shut down. (That discussion leaves aside more circuitous routes through Turkey, Armenia, or Georgia, etc.) The ideas expressed by Zelensky and some Eastern European capitals (but rejected in Berlin) also find echoes in the US right-wing press, should anyone care. The US State department however has rejected imposing visa restriction on Russians. (Both the US and Germany have also made some attempts to attract the recent outflow of skilled specialists from Russia by tweaking some professional visas.) Russia's government position(s) are somewhat more complicated. They have on one hand ridiculed the visa ban measures as doomed to fail, but on the other hand they also issued travel advisories against going to the UK, for example. Also, the functioning of the US embassy in Russia is severely limited (since last October, seemingly due to disagreements with Russia about local staffing) so for most US visas Russians apparently have to travel to third countries, like the EU ones.
