I've worked in these sorts of communal environments for the past six years and never had a problem. I happen to have friends and family who I have occasional disagreements with too. It's just eating together. Can't make it one day? It's not a mandatory meeting or something.
Try missing 20 in a row, because you'd much rather eat with your friends or SO. What happens? The happiness manager comes and pays you a visit is what happens.
Well yeah, if the rest of your company regularly does something fun together, and you can't be bothered 1 time in 20, then you're probably not a good cultural fit.
Like it or not, a workplace is a community. And the norms of communities will differ. There's no need to shit on places that work differently than you're used to.
Just don't work at those kinds of places.
What's more, it doesn't make any sense to assume that your views are the same as "99%" of people without any evidence.
Maybe you just don't work well with that?
