There literally has never been a registered Democrat as FBI director. The January 6th arrests and prosecutions started with Trumps own DoJ. The same FBI you accuse of being a wing of the Democrat party twice tried to incite BLM groups to commit violent crimes. You expect me to believe that was the Democrats doing that?
The big problem with your logic is that all that is that the people you considered persecuted are and still are convicted. Unless they somehow in the future get their convictions overturned by proving their innocence your complaints are nothing more than throwing a hissy fit that criminals were held accountable to the law.
