lol. first off, if lefts are constantly acting like bigots towards republican "bigots", calling them out for it does not mean it's "played out". it just means you're doing it all the time.

That's because the right are always acting bigoted. This is America, and we eat, breathe and sleep racism.

second, advocating violence to get your point means that you have lost the battle through democracy and are turning to violence as a last ditch effort. if you lose an argument, punching the winner doesn't make you right. it just makes you an asshole and a sore loser. lastly, violence against a peaceful rally is going to push more people away from voting and associating with democrats. you seriously think people are going to hear about a violent attack on a trump rally and think "boy, those liberals out in california are probably right. i should vote democrat next time"

That's why I said I wasn't sure about it's practical efficacy. I'm not encouraging any violence - I think it's counterproductive and you're right. But, I do sympathize with the sentiment that drives people to violence.
