The video linked at the top of this thread is the evidence you asked for, have you even watched it? It doesn't matter if you consider that person a viable source or not, it has clear examples of men being demonized by left leaning sources. So much so that it leaks into pop culture/media. Men clearly feel like they are no longer welcome in many spaces, or are lesser/undervalued. I'm not here to comment on whether thats deserved or not, but it has consequences.

You seem to be under the opinion that there has to be a legislative policy or that it needs to have been said by a politician for it to affect someones sentiment, opinion, and voting choice. It doesn't.

This said as somebody who did not vote for Trump, not that I liked the other candidate that much though either. There is clear evidence of blatant hateful rhetoric towards men to the point of being considered okay to just openly talk hatefully about men that by nature of cause and affect has also led to growing blatant anti-female rhetoric, and it is driving younger males towards the right by simple gender divide. The right is just better at capitalizing on it.
