>For all we know, we're hearing the vocal minority of people, instead of the actual voices that need hearing.

Yes, and they have the right to protest too if they feel like their own voices aren't being heard. That's the beauty of freedom.

You can't seriously be against people protesting simply because you don't want to do it too. It's like arguing against voting because some (or even most) people don't vote and those who do are usually more "vocal" or political. It's a very dangerous mentality
