To paraphrase someone else, cited:
The current liberal habit of shamelessly lying about opponents makes civil debate impossible. Similarly, the mockery of conservatives before stacked audiences a la Jon Stewart is part and parcel of the same strategy of delegitimizing any opposition. Closing down the option of discussion leaves opponents with only the option of voting for the extreme (Trump) or action (violence).
As Jordan Peterson said, people who cannot talk out problems can only resort to violence. In that vein, the rational, safe solution is Trump - because the only alternative if Clinton won and instituted totalitarian oppression of opposing views was violence.
