There’s a way this is true but hard to explain unless you’ve experienced it. I think 4chan is much more openly toxic and shocking, but I used to mod defaults on reddit and all the same toxicity exists, except its dressed up in nice language and intentions. 4chan, to its detriment or success, is more accepting in a way. Reddit is full of people who know better than you and want to shame people for being stupid, far more judgemental. Some places on reddit are far better than 4chan though and don’t have this issue,
