There's the toxicity on Reddit on one hand, and then there's the "Hitler was right", casual usage of racial slurs, and insinuations that "jews are trying to stifle Voat" on the other hand.
In the linked post you'll see references to "Angel", an anonymous individual that was funding Voat up until - apparently - March of this year. The comments refer to this individual, in a negative light, surrounded by both three parenthesis and the star of David.
In other words, the level of toxicity is on a completely different level.
I don't see anyone referring to angel with the star of david in the comments. I think the author of the post was simply using angel to refer to their angel investor that kept the platform funded.
Reddit attacks people if they don't have just the right amount of left leaning beliefs for the occasion.
4Chan basically requires you to prefix and postfix all your nouns with certain slurs.
People are mostly the same all over so I assume like 90% of the stupid crap you see on Voat or anywhere else is just people trying to virtue signal to each other and they don't honestly believe that garbage (even HN has its own brand of this) and only a minority of users honestly believe what they type. People are very good at fitting in.
Sure, it looks bad if Reddit is your frame of reference but if 4Chan is your frame of reference then it's just the same old layer of garbage on top of whatever content you're actually there for.
I used to lurk 4chan regularly (granted, not /pol/), and the amount of viciousness and toxicity on voat.co still seems high in comparison IMO.
The way 4chan uses suffixes like "f*g" (which is mostly jocular/memey, even if in bad taste) is not the same as the kind of outright hate speech you'll find all over voat. Voat might be more comparable with /pol/ in particular.
