I fully support people's right to protest. It's a fundamental element of a free and democratic society. As a military veteran I even support people's right to protest and to burn the flag (though I personally find it highly offensive). The reality is that unless the protests inconvenient many people most won't pay attention. If today's protests were people standing on the side of the roads waving signs they wouldn't have gotten nearly as much attention. It is also a way to put pressure on the politicians. Ordinary citizens that are inconvenienced put a call into City Hall and say, "Fix this!"
I was a youngster, but I still remember the Civil Rights movements in the south and my town in Alabama. Nobody got much attention until people started civil disobedience acts. You should have heard the conversations around the dinner table when black protesters sat-in at the white-only diner! The older people were incensed but some of the younger people, and certain religious segments, started thinking that maybe they had a point. Mrs. Winston, who was a Quaker widower, caused quit an uproar when she visited the local Baptist Churches to speak against bigotry. That was only after the sit-ins.
