If you think being violently disruptive loses you support you should look at any equality movement. I'm not posing a false dilemma, I'm saying that when peaceful means are not working then violence will follow. "A riot is the language of the unheard".

The idea that everyone can just be convinced with a good argument is a nice fantasy but just never true in reality. You've also rigged the game since you can just dig in your heels are refuse any argument and just say "get better arguments". It's a situation no one else can win. If people could so easily be convinced that different people deserve the same rights then we wouldn't have had to spend over a century trying to get them.
