One of these things is not like the other...
I can tolerate the occasional "mandatory fun" corporate event, but only within reason (e.g. I have kids, so don't give me grief for leaving early).
And I think the entire "work hard play hard" office culture, where you're expected to do happy hour everyday and build your social life around co-workers in order to prove you're a teammate, is ageist and absolutely toxic.
To be blunt, if you have to FORCE people to socialize with you, then maybe you need some self-reflection on why that's necessary.
