I don't mean to pour any more oil on the fire, but I'm not comfortable with how snark and gossip are described in that statement. Both are activities heavily seen as feminine (the former as an internet thing, the latter in real life). I'm ready to admit that both can be quite problematic, but using the first one as an example to be avoided because it's too close to "white cishet man vibes" and the second one as something intentionally "unserious" and frivolous seems inappropriate to me on multiple levels. So I'd also like to see at least some explanation of what was meant here.
What seems privileged to me is the ability to avoid bigotry. Even as a comfortable first-worlder, I can hardly spend a day without encountering transphobia of some sort, and I'd rather share a laugh about it with some comrades than stew on it all by myself. Just look at the trans megathreads which always contain people recounting their negative experiences, and rightly so. The world often is a hostile place; it's not misanthropy to think so and trying to have a space that avoids talk of popular bigotry in the name of worker's solidarity is, in my eyes, the more privileged desire.
