There’s nothing wrong with criticism or calling out bad behavior. However, shouting “ACAB” in a thread about police violence, making jokes about beheading rich people, or throwing “muskrat” comments in discussions about Elon Musk, just to name a few examples, makes you an asshole and part of the reason why social media is so incredibly toxic.
If you’re doing that while also explaining why you feel that way, then it’s still not the best approach, but at least you’re contributing to the conversation instead of just making noise. Throwing out insults without adding substance doesn’t challenge anyone or encourage meaningful discussion; it just perpetuates the toxic environment that so many of us complain about.
To summarize: You hate phrasing the indicates solidarity. Further, you feel you are entitled to a specific level of discourse and consider anyone who does not pass this gate you keep to be toxic. To that I say: NO U!
