I actually don't think Donald Trump is particularly more sexist than a randomly sampled American.
What I think is sexist is the outsized hate campaign that has dogged Hillary since she became first lady. She's not notably worse by any metric than John Kerry but she receives way more vitriol.
People were saying she was literally Satan. And Bernie voters were saying she was unacceptable due to being a corrupt sellout establishment candidate, but again... John Kerry didn't receive anywhere near the level of hate.
It's a tough issue to argue though, because I'm not saying it's black and white: I'm not saying haters would've supported her if she was a man. It's more of a matter of degree: the anger and malice toward her would've been less if she was a man. The tenor of people's opposition would've been different.
For that reason I don't think you're awful if you don't believe me. There's enough ambiguity that I think you can say "let's call it an open question and focus on more irrefutable examples of sexism".
But the reason so many women are upset is this is exactly the kind of sexism they face evety day: subtle sexism that is difficult to prove, but when experienced over several decades feels undeniable.
For example when he criticized Megyn Kelly as having "blood coming out of her wherever" implying that she asked him a tough question because she was having her period.
The Hillary narrative would have you believe that because he is a man that he is inherently sexist. Only a woman could represent women effectively. And of course forget that Trump had a woman running his campaign and has many high-paid women helping to run his businesses. Many people find the truth inconvenient, hence the downvotes.
Trump doesn't use certain dog whistles and lacks the feminist shibboleths. That doesn't make him sexist. He has no problem hiring or working with women.
The only sexism I've seen this election has been from the hillary camp. Wouldn't it be nice to have a female president? winkwink
You know that is emphatically not the kind of statement that people were concerned with when they were talking about Trump's sexism.
