It's nowhere near as toxic as Twitter, for sure, but there's definitely a toxicity bubbling under the surface. If you stay in "most viral, newest/popular" and keep to the high rated comments, you might never encounter it though.

Just browsing thru images shows this to be quite untrue. Its just a subset of reddit content, also gamed by bad actors. Plenty of hateful and violent content, as well as a staggering amount of misleading graphics as well. Look for yourself, be your own judge.
