LOL. Apparently the OP doesn't really know what Authoritarianism is. This country could use a bit of ut, but no the Republicans are NOT Authoritarians.
Working to not allow gays to marry, Trump saying he will pay legal fees for his supporters to assault protesters, saying he will bring charges to journalists that in his mind lie, saying he will ban all Muslims from entry into the U.S., encouraging violence against protesters, yeah they are authoritarian since Trump will soon be the GOP nominee.
The argument over marriage was to prevent a slippery-slope issue from being created, one of the top no-nos in juris prudence. How do we prevent plural-marriages, beastiality, marriage among siblings now? You can't unless you infringe on the rights of individuals to marry whomever they wish.
He never said he would pay anyone's legal fees unilaterally. I don't even remember him saying it. It was at the suggestion of others.
I agree that the press has been corrupted. It would be a good thing if the press had to pay a price for slandering if malice could be proved in a court of law.
Encouraging followers to defend themselves is not encouraging violence. It's just common sense when you take into account the tactics of Moveon.org and Blacklivesmatter. Doing otherwise simply encourages more attacks.
