It encourages violence, it desensitizes us,

We can understand why that's like, not a very concrete justification to be against espousing violence, right? I also find it weird, right, that we're doing this step-around thing, where you're calling everyone out for the hypocrisy of, oh, well, people are against this violence, but they're not against this violence? Have you maybe considered that the two forms of violence are distinct? Perhaps that the two forms of violence are actually not similar? That people have reasons for, say, wanting violence against one party, but not another?

That's what they're commenting about. You say "it's either all okay or none of it's okay" because it encourages violence, right, but, I am giving you an opportunity to show your work, when it comes to this very basic claim, upon which rests the rest of your argument.
