W supports their right to do what they are doing....but no more than they are doing. This being excercising their right to free speech and their right to protest.
You are not saying that W opposes these things are you?
W would rather them not be there and rather not be dealing with this issue but that is just tough isn't it.
Got a quote where W said the minutemen have or are acting in a vigilante way? No you don't.
