While voting should be done, it is not always effective/possible. An obvious example to bring up is the suffragist, since they were not allowed to vote.

The point of protesting in a manner that is truly disruptive is to force the problem to be dealt with. This concept seems to allude many, to them the only acceptable form of protest is one that is entirely ignorable. I’m not sure we would have many of the important freedoms we have today without people choosing to be disruptive in this manner you find unacceptable.
