"When I am weaker than you, I ask you for freedom because that is according to your principles; when I am stronger than you, I take away your freedom because that's according to my principles." I can't believe in freedom of speech and religion for everyone in light of people who would use that belief against me for their own gain. This is less about the ideas themselves and more about how they invite clever opportunists to take advantage of them and get rid of free speech and religious freedom once their usefulness has run out. The best way to protect a society from this kind of problem is never to have such values baked into society's foundation in the first place. If the ideas America followed brought it to this end, maybe those ideas should be discarded.
