There is nothing wrong with being seen or heard. Instead it is that being violently disruptive tends to lose you support.

You are posing a false dilemma where the only thing a person can do to voice there opinion is to destroy or disrupt things.

That's not true though. Instead you can simply voice your options. You can put out manifestos, publish articles in the newspaper, post to social media, or even talk to people in person.

All those methods are how speech and ideas are normally distributed in a normal society. And if people aren't convinced by what you say, then it is time for you to get better arguments.

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.
