I don't even consider their behaviour left-wing, I think identity politics is a right wing tabloid interpretation of left-wing policies - in other words, not actually left wing.
Identity politics is born out of a combination of right wingers at the top who want to keep us fighting amongst ourselves, and poseurs who want to make a name for themselves.
Guys like George Soros LOVE identity politics because he is a right wing bastard who doesn't want people to band together and battle the REAL cause of inequality in our society. Class.
So he funds things like the woman's march, the LGBT march because that keeps idiots fighting about things like gender pronouns, turns women against men, and men against women as it leads to moronic things like MGTOW, splinters people into ever more tiny little categories like LGBTQYTERXEZ24397 etc, all instead of uniting together against people like him.
Its like that line from Working Class Hero "Keep you doped with religion and sex and tv. And you think you're so clever and classless and free. But you're still fucking peasants as far as I can see." Replace religion with identity politics, and
There you go. Still fucking mindless peasants, squabbling about the stupidest shit.
At the same time you also have soft, scared, wimpy little upper middle class spoiled brats who want to appear as revolutionary's, but are too scared or stupid to make any kind of proper analysis that goes against the received wisdom.
So these people like Anita Sarkeesian, will pick out easy targets, battles that have already been won, and with a little media manipulation look like they are actually fighting for worthy causes.
Sadly the media is always on their side as they are a pack of shameless cowards when it comes to fighting for things that need fighting for, and they are also the most disgusting misogynists too. Ironically the mainstream media is one of the last examples of institutionalised sexism in western society.
Still the media props these people up so that it can say to its critics "LOOK WE'RE NOT SEXISTS, WE SUPPORT FEMINISTS, WE HAVE AN "ANGRY" FEMINIST WRITING A COLUMN IN OUR RAG"
As a result its the phoney feminists and leftists that have had the influence on the next generation. Instead of John Pilger and Ayan Hirsi Ali, its fucking Caitlin Moron and Anita Sarkeesian these people listen to which has turned left wing politics into the joke it is.
The best thing to do is abandon the left, but not your left wing principles IMO. The right are every bit as bad. They are just as racist in their own way, just as tribal, and would shut people down if they could (they already did with McCarthy who many modern day right wingers like Stefan Molyneux and Sargon of Akkad try and paint as a great guy.)
Really these days as pretentious as it sounds I'm just a free agent, not linked to either. Doesn't mean I'm a centrist however, as centrism is another tribe and can easily lead to the worst aspects of both the left and the right being utilised, which indeed we see in our government today, which goes in for SJW, identity politics crap with its "don't criticise the laughably incompetent Theresea May because she is a woman", whilst imposing the most Draconian policies on the genuinely underprivileged, poor and disabled in our society.
