it was the *DEMOCRATS* who refused to sit some delegates simply because they were the wrong sex
Yeah, the Democrats have a policy concerning equal numbers of each gender which the Vermont delegation initially violated. Not seeing an example of sexism here, but an attempt to avoid it.
"Racist" is thrown out by the left so often it no longer has any meaning.
I'm pretty sure it does, it's just a sizable number of the right, particularly the alt-right, both understands that "being racist" is considered bad, but that they have no problems with a society that deals black people the short end of the stick, that they have an irrational fear of brown people, and even - in some quarters, most Republicans don't fit into this category, but many on the alt-right do - that they're worried about the influence of Jews.
