Why can't the FBI on order from Biden just break up and jail the leaders of these hate cult groups like Q-anon? The gov. does nothing.?

i think if theyre dangerous they should go to jail too

If all they do is talk, the First Amendment to the US Constitution.  
If they take measures to massacre those they slander, they can be arrested and subject to due process.  
I really don't know what the Qs say, they have such a small voice.

It is about process.  Arrest, charge, indict, trial.

This is the RE-LIG-ION section, you halfwit. 

The group known as qanon isn't real it doesn't exist.
It would also be illegal to just arrest people for saying things you didn't like.

How about we get rid of all the religious people. You are the ones who hate the rest of the world. I am tired of your world views. You are racist and uncaring. I don't agree with your TACTICS. You don't love God only your religious beliefs.

QAnon content isn't really the point. They exist as a 'check and balance' to the mainstream Press after it abandoned its oaths of political impartiality and became a one-party ultra-biased voice for the Democratic Party.

The easiest way to get rid of QAnon or other groups like it is to have the mainstream Press return to its oaths. We live in a system of liberty, which will automatically create a 'counterpart' to whatever asserts power within the system unchecked. If you lie and cheat within the system, it holds up a mirror to you and shows you what you create when you do.

The FBI is a communist style bureaucracy that needs reformed like all bureaucracies. It was formed and managed by a transvestite, has a history of 'accidentally' burning women and children alive in their homes while trying to disarm people, routinely goes undercover to sell drugs to children to 'catch bigger fish' and is currently outnumbered 100:1 should it decide to hunt down and imprison law-abiding American gun owners.

I think you were looking to ask this question in the Government or Legal section.  However, you should start small and try to understand the concepts of due process, burden of proof, innocent until proven guilty and, of course, freedom of speech.

You're almost on the right track, as the strength of freedom of speech is to allow idiots to speak their mind and then show how idiotic they are. But that position is strengthened by doing so in the best manner possibly, rather than random rantings.

Lets start with those on record, who actually exist, who did just that like Pelosi and Waters! Then lets end it with having the Democrats step up to "their" charges like the Republicans have, and been found innocent. Then you can address the fabrications of the truly stupid.
