Why is zionism so bad on reddit?

I'm not looking to start any drama here, honestly this is a question I would've asked on the autism sub but I just cannot trust that sub to be free from zionist bots. Social media in general is awful but reddit seems by far the worst, every sub is just infested with bot accounts dedicated to defending Israel and I don't really understand why, or atleast why this isn't something normal ppl are pushing back against. I just saw a post about a father who was killed just outside the hospital where his son was being born and instead of people being sympathetic, and understanding it's a horrible thing, all of the replies are spewing Israeli propaganda. I genuinely just don't understand how reddit has gotten so bad for this, it makes me sad.
