Because the entire US political spectrum fits nearly inside of “neoliberalism”. Liberalism in general is just capitalism+.

It’s common for chauvanists to side with the US Empire’s claims about Tibet, Xinjiang, and Taiwan, as well as the framing of these issues. For westerners who utterly lack the background knowledge required to even begin untangling these subjects, to side with the world’s largest Empire against a rising socialist country it has every means and desire to lie about, this teeters into chauvanistic territory. I think anyone trying to get a realistic view of these subjects needs to also explore the Chinese perspective, as well as the global south.

Marxist-Leninists don’t hate everyone, we have a deep love for the working class and a hatred for oppression. The reason MLs can seem hostile is because we have to deal with the same arguments day in, day out, unceasingly. This manifests in frustration, lashing out, etc. It gets increasingly frustrating when Marxist heroes like Marx, Fred Hampton, Che, Frantz Fanon, Walter Rodney, Rosa Luxemburg, etc get passes from liberals due to their martyrdom or dying before being in a position of influence, while liberals follow the US Empire’s line on existing and practicing Marxists, and those who lived long enough to succeed.

I’m a Klansman because I lean to supporting Taiwan’s independence?

Taiwan is pretty much if the US confederates lost the civil war, then escaped to Cuba, killed all the people there, and set up a state. Read about what mass killings the Kuomintang did to the indigenous peoples of Taiwan when they escaped there.
