I find that the person who is the most danger to your freedoms isn't the ones who disagrees with you loudly. You can identify those people, and watch what they do, monitor their progress. You can engage them, have a dialogue, and perhaps eventually, persuade them or their followers differently.
The person who is most dangerous to your freedom is the person who won't publicly commit to anything, who is vague and who sometimes try to hold two opposing opinions. They don't really feel strongly about anything but themselves, and have no compunction about selling you down the river. It's all about them, don't you see.
Without a commitment to a cause, people like that have no reason to stick to an unpopular opinion when the going gets tough.
Mitt Romney is one of those people.
That appears to be true on almost every issue. Mitt is a master dissembler.
