It is a toxic wasteland, though, at least sometimes. Also depends on who you are and how you experience the world - HN can be a very ugly place.
HN is no cakewalk. There are lots of very vocal climate deniers, homophobes, Nazis, etc. here. I've been called hateful slurs on HN that nobody has said to me anywhere else. Much of this flies under the radar of the mods and the users are frequently not warned or banned.
HN suffers all the same problems as Twitter or any of the others.
