Yes, if you imply that Donald trump is guilty of actions those associated with him have taken, you are using guilt by association. It's definitional!
I understand that you feel strongly about this, but it's not illegal to hate someone. If there are people being threatened or harmed, we do have police and the general rule of law to handle those things. It's not like trump runs the government now!
Despite emotional currents we are mostly peaceful domestically. Our institutions are still democratic in nature. Trump has to share power with the other pillars of government.
We are very, very far from anything resembling naziism. No amount of hatred expressed in speech is equivalent. Action is required.
