Sure but socially competent people don't dominate a conversation with complaints, it bums everyone out. And meeting in real life means these are people who you'd have a high chance of running into again, so folks tend to behave better.
People online pick up others' complaints, then parrot them into every other relevant thread to farm internet points.
If they're all on the same page, how do you feel about excluding any single component of this group from private property? Is it ok for businesses to exclude the unvaccinated? How about the others? If not, is that infringing on the business owner's right to self?
I think a lot of people would say it's ok to do that to some and not others, which means these groups can't be on the same page.
