But I've seen people yelling at someone who's been there for the first time and is disagreeing with something for the first time, not "consistently disagreeing" with "the most important things the community agrees on" (whatever that is supposed to mean in the context of a group of individual, supposedly critically thinking people).

I get what you're saying about misogyny, but on the other hand, implying that I must reconsider my points of view simply because a group of other people happen to disagree with me, sounds kind of disturbing to me. Exactly what kind of community is that? A place where people present their opinions for discussion, or where you have to adhere to certain opinions as an obligatory condition for being "accepted"? If it's the latter, then I'm not interested.
