Neo-Nazis aren't just people with opposing views, they are people who believe their race is superior and others should either be exterminated or subservient to them. They are people who want to take away your rights if you're not like them. American can't let these kinds of people gain any credibility. They don't deserve to have their opinions heard or their safety ensured. Let them be stamped out immediately.
TL; DR HATE SPEECH HAS NO PLACE IN THE US
