Why do people waste time on anti-war protests?

[Danny_C]

And you forgot to add to your list:

people who care about the lives of others and know the political impact that large-scale protests can have.

And if you think protests are useless, consider Vietnam. Whether you agree with them or not, they do make an impact.

I do agree they won't prevent us from going to war, but it's going to be a much different war than it would be with everyone behind it. War is politics.
