YouTube's updated policy:

"Our products are platforms for free expression. But we don't support content that promotes or condones violence against individuals or groups based on race or ethnic origin, religion, disability, gender, age, nationality, veteran status, or sexual orientation/gender identity, or whose primary purpose is inciting hatred on the basis of these core characteristics. This can be a delicate balancing act, but if the primary purpose is to attack a protected group, the content crosses the line."

Note the last line... If you are not in a "protected group" then I guess all is FAIR GAME.

Noted apparent unprotected groups:

Trump Supporters
Gun Owners
Political Affiliation (unless they identify WITH one of the "Protected Groups")
Supporters of The Constitution

It says "Religion" is a protected group, however, if principles published are perceived negatively by "protected groups" that is harassment. And this, of course, is not reciprocated.
