Neo-Nazis Fly Under Radar

[Tiberius]

Indeed, however, what about the right of a group to lobby for the overthrow of the government and replacement with an undemocratic institution?

Knowing that said hypothetical party would deny the rights it uses now to others, does it still deserve a fair hearing?

I think not, as their rights end at someone else's in my view. And their right to lobby for changes in law ends at attempting to steal the rights of others.

In my opinion, they do deserve free speech. In order to have free speech, we must run the risk of losing it. The problem I have with your argument is that you can adjust it to cover anything you (or the government) doesn't like. Say gay marriage is legal; should it be made illegal to protest gay marriage, or to lobby for a law that bans gay marriage? That would surely be an attempt to steal the rights of others, so why not ban that?

Then you get a very slippery slope. People see their rights differently to others. Rights often conflict with each other too.
