Somehow, I suspect that if the story were about primaries to the Democratic State Senators in New York whom refused to support the Leader candidate chosen by the caucus in favor of a coalition with the GOP I doubt the headline would be, "In New York, Liberals Vilify Fellow Democrats." I suspect the title would revolve around ideas of righteous indignation.
The difference is that your side is full of wackjobs who say crazy things and demand their right to "reload" and not to retreat. Liberals don't threaten to kill people...
