Using that logic, everyone who supports cops or the military using guns is a supporter of gun violence, and anyone who supports physical self-defense is a supporter of violence. Makes the notion of "supporting violence" politically pointless.

Yeah. Everything has a trade-off. I don't want swimming pools outlawed, so I have to accept that ~350 toddlers are going to drown accidentally in pools every year. That does NOT mean I support toddlers drowning, I just tolerate it as a cost. It's not like Kirk wanted deaths from gun violence.
