Internet toxicity can entirely suck the fun out of participating in a community, thereby defeating the purpose of participating in it.
But, similarly, a really fun community can do the opposite. I used to participate in the Ruby community more for the people than anything else. I never actually loved the language all that much.
A) What makes you think it's a teenager? The internet makes even ordinary people act in ways they would not act IRL.
B) It's completely reasonable to avoid something because you don't like the community. Comments like the quoted one in GP post are definitely not rare from the Rust community.
the rust community can deal with caustic advocacy or they can do nothing. they've chosen to do nothing, from what I can tell.
accordingly, I've chosen to stay away from that product and its community.
this is not a crackpot point of view, this is the point of view of a sane person who realizes that his time on earth is finite and who has zero appetite for games.
