Of course I'm serious. Outlawing them will put an end to their abuse of the law to conduct witch hunts against innocent people.
You are silly and serious then.
When the leader of one political party outlaws other political parties, it is called a dictatorship.
I don't want the United States to ever become a dictatorship.
I would never call for the Republican party, or any other party, to be outlawed. I care about democracy.
Your call for a dictatorship is serious.... but given that (God willing) it will never happen here, it is also silly.
