A Nazi is somebody who places his own believes about anybody else's with no mercy. More or less from Robert A. Heinlein's Friday. As usual, he was right.

The only problem is that the not to numb Nazi uses the freedom we have to wrap his ideology into it (that is the fight censorship part, for example). Any democracy must fight this. Are it will find itself in the hand of the Nazis - and they will show they true face. Then there will be only there rules, and one will learn what censorship means. It is as simple as this. Freedom needs limits. And outright lies, misinformation and so on as spread by them in any amount must be censored and erased. It's hard to violate own rules, but there is the border.

It is not wrong to use such channels, but one must be very very awake to not fall into the traps. It's very subtle, and on first glance not wrong. It is not unwise to stay away. Quite to opposite - one should question friends inviting one to places known. You wouldn't go into your towns major place to deal with drugs because you are invited, wouldn't you?
I live in a town that has strongly suffered from the last great outbreak of those idiots. A simple view out of the window will show a church bombed. 75 years ago. I can do without. Resist the beginnings!
