I don't agree with the gatekeeping of the take from a literal point of view, but rather I think that the sentiment of "It is reactionary to support exploitation and oppression, and it is hypocritical to claim that you oppose it while still continuing to support it" that leaks from it is spot on 
Also, I gotta love how someone posted two separate comments within a minute of each other just to articulate a very short point of this take being "ableist." That's 100% indicative of seething.
I also love (this time using this word unironically) that she's a fellow black vegan communist who is sick of non-vegan leftist bullshit.
The reactionary right have re-categorised "class" in society away from economic analysis and into a cultural one. Working class becomes a vibes-based behavioural attitude based around how vulgar and unpolitically correct you are while middle and upper class who behave in a less vulgar way become the "elites" and they're the cultural enemy trying to force their ideas of behavioural norms on you. To the reactionary right these middle and upper class groups are identified through the brands they consume like Starbucks, veganism, or caring about animals or even caring about other human beings.
This consciousness of this made up concept of cultural-class that they infect people with becomes a blockade to giving them real class consciousness.
