Don't watch it then, problem solved.
Dude, you always say this and it's getting old. Because one could easily argue that if you want to watch people get punched so much why don't you go watch boxing or MMA.
I'm not here to try and convince you that fighting is dumb, or bad, or whatever. It wouldn't work even if I tried. But please stop with the "if you don't like it don't watch" argument, because it's not a very good one and is basically the adult equivalent of taking your ball and going home.
