And that demonstrates that all the leftist groups are not filled with Russia and China supporters… how?

Because it’s clear you’ve never talked to any leftist member of any leftist group ever?

You’ve completely made up these big bad “Russia and China” supporting “leftists” in your head. Every leftist space I’ve ever seen in person is full to the brim of anarchists. You have to go out of your way to find these people you think are rampant in leftist circles. What you read online isn’t how it works in the real world. You need to get out more and stop believing all this anti-leftist propaganda you’re reading online.
