Oh puhleeze. Any discussion of he-said, she-said to prove which is more hateful is futile. We all can find hateful examples on all sides.
As a generalization though, Leftist are by far the most hateful of all.
Most colleges skew left (fact); most colleges don't invite, disinvite, or downright protest and harangue conservative guest speakers. (fact).
The Left always labels as "haters" anyone who propones objective  standards, particularly when it is on the Right or Christian side. Yet they themselves are intolerant of opposing views.
Neither side has a monopoly on hate, intolerance, or high-horse. But the Left by far has a lot worse record on this than the Right does.
Case in point: A heck of a lot more protest rallies and marches just went down this weekend because their gal lost the election. No where near as many marches (I can't thik of a single one, actually!) ever happened after Bill Clinton's, Jimmy Carter's. or Barrack Hussien's inaugurations. COMBINED.
So get off ur high-horse!
