I think it’s saying white people telling indigenous people how to live is touchy and to not be weird and racist about it
That image was also used in a class that taught us about how white people systematically destroyed a specific indigenous way of life that relied on following or at least relying on the migratory patterns of buffalo.
That society had a much better grasp of living in harmony with nature (not destroying the biosphere) so white vegans today are arguing from a bad position when whites arguably destroyed a much better way of life than veganism under capitalism.
While it doesn’t come up as often as carnists would claim opportunistically, white vegans are still white and should defer to POC vegans and at least be highly cognizant of their privileges when criticizing non-white people (especially considering carnism is higher among whites than non-whites). Especially considering white people are chiefly responsible for culturally exporting carnism as a power signifier to begin with.
I have talked to plenty of white vegans that being vegan does not give one permission to be racist, nullify their privileges, or grant them moral license to be domineering or wield their privilege when talking to non-white communities, they should be on their best behavior as an ally and conciliatory the same way queer whites should not be domineering when entering non-white spaces, including cishet non-white spaces.
Being vegan is being vegan.
It can compliment but it is not a substitute for becoming anti-racist. Moral license becomes a conductor for suppressed racialized hatred. Communists are not immune.
