As has been said its less the label in itself and more the "stupid white man" fashion in which its come to be used.
I mean clearly there is a lot of transphobia around and you see a lot of it on Sherdog(it clearly feeds into the insecurities of alt right/alpha types who are over represented here) including this thread but I think the universal nature of the insult and the obsession with language does have an elitist bent to it.
The kind of liberalism that's most popular with in mainstream politics and media tends to have an unpleasant side to it that's disrespectful of much of the working class population. I think the reason is obvious, those at the top want to carry on an economic system that benefits themselves at the expense of such people so promoting a world view that's negative of them obviously helps that, why would you want to help someone working part time at walmart and living on a trailer park? he's probably a filthy racist, sexist transphobe, its YOU who are the oppressed one. Don't vote fo Bernie Sanders he's supported by sexists.
The reality for me is that the people at the top don't just know there tactics end up forcing people into the arms of the far right they actually want this to happen. The more they create this environment the stronger there argument can become and we see it on politics becoming more and more partisan.
As has been pointed out politics have become much more partisan over the last 20-30 years yet I think if you look at key issues in economics and foreign policy the two parties have actually moved closer together, indeed I would say even social issues whilst obviously divided are less divided than they would have been in the mid 20th century. If your in that situation were a large part of the population basically has nobody in the politican mainstream to represent them the obvious answer is to distract them with partisan debate on social issues, basic divide and conquer tactics.
