If elevating your voice is merely annoying people in an attempt to advance your cause, I think you’re well within your rights. You’d certainly be in good company, although it’s hard to see that you’d be winning many hearts and minds that way.

But when you find the law uncongenial to your high moral principles, and commit vandalism, arson, block traffic, occupy buildings or any other crime, then I don’t see why you shouldn’t be treated like any other criminal.
