Extremism on both sides
There is as simple argument that goes unnoticed.
While an insult plainly voiced would be considered toxic. A politically correct way of voicing an opinion without including any insults, but with the same
message would not.
These people act like they are so serious, just like most social media. That's why I believe toxicity is a good thing, because it teaches people not to take everything so seriously. And I would very much prefer a person to tell me to kill myself directly, rather than them ramble on about how it is their right to hold an opinion, acting better and pretending like I do not have a reason to be upset.
