American "leftists" aren't really leftists, but just center-left liberals. Real socialists, and communists, aren't environmentalists or tree huggers, we believe in industrialization, using nuclear energy, science, and technology. We're materialists, so the idea that a male can just declare himself a "woman" and become an actual "woman" is seen as absurd, if not dangerous by the genuine leftists.
We don't inject our children with puberty blockers. What we're witnessing here in America with these liberals in many ways is funded by big-money capitalists like George Soros and other liberal billionaires. They want to emasculate the male population and get boys hooked on expensive hormone treatments and surgeries. It's all a very lucrative business and a way of controlling the masses. Turning everyone queer makes people more naive, gullible, complicit, submissive to the establishment, less rebellious, and objectionable. The American liberal ruling elite is doing everything it can to castrate the working class.
