Well that’s… needlessly hostile?

Vegans are aware of the damage the supply chain does, hence “buy local” being such a common phrase and the push to support small local farms. I’m not sure what you’re accomplishing besides hilighting that capitalism is an awful economic structure that incentives profit over environment, which sure good message, but most people choosing to adopt such a culturally despised practice are going to be aware of the blindingly obvious externalities already.
