No, they want to cleanse the bourgeoisie, they're very multi-ethnic in their genocides. And not all of the far left is colorblind, we generally consider people who want to ethnically cleanse white people as far left.
They specifically advocate for inclusion of races, and a destruction of a class system. Nowhere in this does "color" or "ethnicity" make its way into this.
Please point me to posts on those subreddits calling for a bloody revolution and the killing of the bourgeoisie? There's been this new meme circulating on right-wing circles that if you are not a card-carrying alt-righter then you must be - by necessity - Che Guevara's second coming. It's pretty disingenuous, and quite silly to be honest.
No, there's a meme among normal people that if you violently riot and attack people and property when you don't get your way politically, you're a nuisance to democratic society and have more in common with the Red Guard than soldiers who stormed the beaches in WWII.
