I mean yeah saying someone should be nuked is pretty braindead and that guy probably gonna get his teeth kicked in sooner or later in his life, but the "no one is forcing you to read it" is just a dumb thing to say in general. Going through life ignoring things that make you feel a certain way, especially if it's a negative feeling that needs to be addressed, is the worst selfcuck thing you could do as a person. That's a good way to build your character into never ever giving a shit and making it so you become emotionally impotent and someone that can't get passionate about anything anymore.
You just don't want to be in that place. There are already way too many people that spend their lives like that every day, it's the worst fucking advice you could give to someone. Yeah talking shit in public will get you into conflicts but that's just part of growing as a person. It's way better than being some kind of online celibate that always does their best to hold themselves back and stand on the sidelines.
