In these instances many of whom (but not all any means) would be white, many of whom (but not all any means) would be male and many of whom (but not all any means) would be heterosexual. Yes. But also many of whom (but not all any means) would be working class, many of whom (but not all any means) might not have had access to Higher Education and many of whom (but not all any means) might live in areas of deprivation (as far as community resources, amenities, etc etc go).
Your point?
People who are shat on and are white, working class are shat on because they are working class, not because they are white. The elite spin some distraction bollocks claiming to support their class (Theresa May has been laying this on with a trowel, just as staunch prolrtarian activist George Osborne did before)
The far right have long pretended to act on behalf of the working class, while being instinctive enemies of the class through, among other things, union busting, nationalism etc.
So in the wrong circumstances it's easy enough for a hoax alternative to be sold, whereby the establishment also promotes that alternative as "anti establishment", look at the efforts made post 2010 to say that UKIP were a northern alternative to Labour (not overlooking Labour's own failures to represent)
For all this, a lot of the moaners of the alt right etc. aren't relatively disadvantaged in any case. They do indeed tend to be white, straight males and are often not very economically disadvantaged, especially in world terms. What they are is martyr myth wankers, not even neccessarily stupid but very eager to suck up and bolster horseshit memes.
There's so much over simplification in this debate. For example, this "liberal elite" meme that is all the rage, pushed by Theresa May so be very careful of buying into it. I know plenty of liberals. None of them are in the elite. But you know who stands to gain from the victory of that meme? The authoritarian elite. As a result of what the establishment defines as "anti establishment" votes, large amounts of extra power have been handed to parties who have dominated their countries for centuries. You couldn't make this shit up.
