Having the right to attempt to defend yourself in court - even if you're a shitty person/organization - is very American, yes. Electing governments in part to try and prosecute said shitty people/organizations is similarly quite democratic.
I'm not arguing they shouldn't have the right to defend themselves in court, only that most people wouldn't think that as being "patriotic". It's also not hard to find people characterizing Citizens United v. FEC as "undemocratic", even though it theoretically emobies the democratic principles of free speech and the supreme court acting as a check.
