I don’t really understand what you’re trying to accomplish with this policy? I can’t think of any social dances that exclude unvaccinated people because the organizers find anti-vaxxers annoying; they’re trying to reduce infection risk.
There are (at least) two channels at play. Unvaxed people are more likely to spread Covid. Visible acceptance of anti-vax sentiment is more likely to attract more unvaxed people (and likely to reduce boosters among the ambivalent vaxed). When you’re not checking vax cards, you can adopt policies that make vaxx the default, obvious preference, even without formal enforcement.
I think antivaxxers could plausibly pose a higher infection risk because they’re unusually likely to hang out with other unvaccinated people, or to do other bad decisionmaking. Someone who’s unvaccinated because they’re scared of needles might still make good decisions otherwise—like they might stay home if they’re feeling a sniffle, or test themselves for COVID if their housemate is sick.
Also, you want to exclude unvaccinated people because they pose an infection risk, so you already wanted to exclude anyone who posts “I hate vaccines” on Facebook. You’re just worried about the incentives or selection effects if you use an honour system, because some people will lie and say they’re vaccinated when they aren’t. I’m suggesting that the incentives or selection effects aren’t as negative if you only require silence, so nobody has to actually lie.
