I think you probably agree with the original commenter that school shootings have killed more than the coronavirus (within the age group). They are saying, if people don't really care about the former, it's not surprising they don't care about the latter, which has killed fewer people. Are you really disagreeing with what they said or just the tone?

You know, I actually think you've got a point to make and I can see the shape of it, but you're so inept at expressing yourself that you come across as either completely misunderstanding or just plain wrong. I guess this is still an insulting thing to say, but at least it's not wrapped in snark or passive-aggression.

I genuinely can’t tell if you’re making a bad argument, or if you still don’t get it.
