Liberals/Democrats, classically, were the party of the little guy, the working class. The working class has been being destroyed ever since NAFTA. Thinks are getting worse and worse for them. The Democrats should have been running on how the economy effects the little guy. They should have been the ones screaming about the price of eggs.
Instead, the impression everyone got was that, if you're working class but you don't think gay marriage is a good idea, or you don't think trans people belong in womens' bathrooms and on womens' sports teams, or you don't like abortion, then you're a moral leper, and the Democratic party is committed to the total eradication of your viewpoint and culture.
Unsurprisingly (given human nature), a bunch of people on the receiving end of that decided to flip the Democrats the bird, and instead voted for the guy who at least pretended to care about their concerns.
So, yeah. There may be "reactionary masculine pushback", but I think it's more pushback from the socially conservative section of the working class. Those people are supposed to be the Democrats' core constituency, but the Democrats quit listening to them.
