The United States is a Constitutional Republic with rights explicitly enshrined therein, including its amendments. You are more than welcome to your opinion on violating constitutional rights but if you want the rule of law then you should follow the constitutional process to add an amendment in order to revoke said rights.
> So, you are opposed to government surveillance of neo-nazi groups that eschew violence, then?
Yes! You either believe in free speech and freedom of assembly or you don't. If these groups are a clear and present danger, show probable cause already. If they aren't, counter-protest, shame them, embarrass them, whatever.
More often than not, hate groups can't help but cross that line to violence or are already linked to violence. It's really almost an oxymoron to talk about neo-Nazi groups that "eschew violence" since they almost always believe in genocide and the violent overthrow of the government and are working towards it. I know it's a tempting rhetorical device, but it's really a strawman.
Tell me: which constitutional rights are violated by the police reading your public twitter feed?

And how are you supposed to obtain probable cause, if you cannot even read people's public twitter feeds? Can you read their public websites? Their leaflets? What kind of research exactly is the FBI allowed to do on these groups?

Pro tip: pretend like your free speech is out of favor with the current extremist government.
Oppose tyranny.
This part of your comment really, really rubs me the wrong way. Your personal inclinations absolutely cannot direct the apparatus of state on a whim. Either those groups are suspected of criminal activity or conspiracy to commit criminal activity, which is probable cause for surveillance, or they aren't.
