The thing that needs to be understood with regards to "defense" of people like Vic is that a significant percentage of people don't believe that sexual harassment exists. They think that the entire concept was created as a way for women to attack men, and therefore any woman claiming it is lying by default. Thus the constant demands for "proof".
In order to understand their thinking, you basically need to shift the entire concept down a level. Rape is "sexual assault", sexual assault is "sexual harassment", and sexual harassment is nothing. Anything below violent physical assault is innocent flirting. Therefore, even if you were to somehow obtain "proof", they would dismiss it immediately.
It's extremely frustrating to watch this over and over again. When it came out that Nick Robinson, formerly from Polygon, had been creeping on basically every woman in the games industry and trying to "negotiate" his way into having sex with fans at events, there was this constant droning noise of "oh, that's it? he was just flirting, shouldn't ruin a guy's life over that". Find a recent story about Christine Blasey Ford online, about how she's had to move multiple times to escape from doxxing and death threats (nevermind the actual, original problem), and you'll find hundreds of comments alternately claiming that there's no proof that she's been threatened and... threatening her. Look at any example of MeToo, and you'll find... these.
The very concept of equality is political, currently. To many people, the idea that all humans are equal is like a white lie, something you say to be courteous. They never actually believed it. This is what people tend to mean when they complain about "political correctness", the implication being that it's not actually correct. That is the reason why harassment and bigotry are always controversial, and the reason why right-wing types rally to defend anyone who is accused of such things. To them, these are lies forced on them by some unjust, shadowy cabal, and they're just telling the truth.
