We all know who makes the weapon and what AR stands for. Assault Rifle works for AR too though.
The government can ban semiautomatic weapons if it wants, or most likely require magazine sizes 5 rounds or less for all weapons (lot's of work for gunsmiths modifying old magazines and weapons). If the government can control maximum caliber size and ban automatic weapons, it can ban semi automatics including pistols, this can be done constitutionally too. Why wouldn't the democrats do this when they take power? They would not lose a single vote over it, every unreasonable gun nut is a Trumper. They will start slow though and work the cock gently into yer asshole with lot's of lube to ease the pain, you'll still squeal though!
Hunters and other legitimate gun owners won't mind so much, statistics show they support tougher gun laws and most don't give a shit about AR's and AK's or want them off the streets.
Racists cling to their guns the most, the same fear born of a deep sense of inferiority drives both things, racism and gun ownership. Those who are against immigration are afraid to compete with the brown folks for education and jobs for a reason, deep down they know they can't cut it. Trumpers know they are white trash and Donald Trump is their white trash president, they are his base and they are base indeed, all traitors are.
