Basically, Leftism has been at war with itself ever since the bourgeoisie who supported the French and American Revolutions ran afoul of the socialists. Both are leftists, but one is more leftist than the other. The former counted as leftists when put up against the monarchs, nobles, and religious leaders, but when the socialists showed up, the bourgeoisie capitalists suddenly became the right-wingers, lumped alongside the religious leaders, the nobles, and the kings, even though just a few generations ago, they were the leftist heathens going up against the divinely-ordained system of monarchs under God.
It's as if leftism is just an inherently unstable and violent system that always seeks to re-invent itself by attacking those that used to carry the movement's weight in the past. No matter how leftist they were, they just weren't leftist enough. The Communists of yesteryear saw the homosexuals as capitalist degenerates. Modern Socialists and Communists see them as brothers in arms, at least in the west. (In the east, it's another story, since Chinese Communists are more old-school; they despise gays and racial minorities just as much as the old USSR and Che Guevara did.)
Back in 2010, I considered myself a somewhat progressive person. I liked strong women in games and other forms of media, back then when "strong women" just meant "a person who is strong who happens to be a woman", not "a woman who has everything given to her from the start but we'll pretend like she is some kind of milestone despite having few struggles and even less training". Now, I run across old feminists who used to be for the movement back in the 80s and 90s, whining about how the left abandoned them in favor of the trannies and race-baiting.
That's why someone like Lindsay is destined to become a pariah. She's spent all this time attacking the right and supporting leftist feminism, but what she doesn't understand is that the movement is not her friend. The movement will sell her ass out if it means scoring woke points with the newer crop of leftists who see old-school "transphobic" white feminists as Trump-supporting Republican devils. Which means that the right will hate her, but the left will end up hating her, too.
