You can't call anyone you disagree with a Nazi just because they are a Nazi. Nazis are not Nazis, they are just concerned citizens who have the right to free speech and whose voices should be heard.

The real Nazis are not the Nazis but the left who uses Nazi methods such as being rude and uncivil to Nazis. The left is just as bad as the Nazis so the left should be condemned just as we would condemn the Nazis if they were actually Nazis.

I hope this clarified things for you.
