There's other arguments like veganism can solve hunger since animal products seem less efficient with land. As a natalist, someone who wants to increase the population, I do support animal rights. We're going to need more food to feed more people.
I guess it's murder. But so is the death penalty. And the death penalty is good. I don't know why some people try to make them seem like they're one of the good ones for opposing the death penalty. Patrick Henry said, "give me liberty or give me death." If you won't give prisoners freedom, give them the death penalty. I think the death penalty is pro-life because it would extinguish that which has no quality of "life." Or maybe I'm too much of a pessimist. As Barry Goldwater, "extremism in the name of liberty is no vice at all." Prison abolition is extremism and it's about liberty. I don't know why some try to virtue signal about opposing the death penalty when it's so rare unlike abortion. And abortion is bad.
