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.
We live in a consumerist country where price is a function of politics rather than material costs.
So "veganism" is just an overpriced branding exercise while surplus hamburger meat from industrial over farming of livestock is some kind of staple crop to the economically illiterate.
The idea that we're being price gouged coming and going, and a bunch of cheap meat is effectively just repackaged industrial waste, doesn't register to meat heads.
