Why you see swastikas in America but not Germany

"Damn shame the U.S. has yet to illegalize Nazism."

That it hasn't is what makes us the great country, despite our present challenges, that we are. All one accomplishes when one makes an ideology illegal ... is drive it underground. Far better to confront it and challenge it in the light of day.

I'm going out on a limb on this one. IMHO why "Nazism" isn't illegal in the United States has something to do with the fact that we have some chuckle heads running around claiming to be "Nazis" but really are not. Just because you run around in jack boots, claiming Hitler was great, and imitating a salute used by the actual Nazi party doesn't really make one a Nazi. It makes you an ass. Kind of like when I was eight running around with a steel pot on my head, a toy machine gun in hand, and a shirt with some Sergeant stripes on it really didn't make me in the US military.

Free speech and the First Amendment prohibits government censorship. Allowing the monuments ot remain despite the fact that they were erected to memorialize white supremacy and are used as rallying points by those people today may be a reason to keep them. One, so that current US citizens see how that ideology one blanketed those areas. Two, if they are still being used as rallying points by racists it will allow those of us who oppose that ideology to see how much work is still left to be done to combat those views. Erasing them from public view will not necessarily erase those views from some people's minds, it will just make it more difficult to see how prevalent those views are and to combat them so they do not come back into mainstream thinking.
