It has become somewhat of a thought terminating cliche I will agree. In the context of my comment though I think it's appropriate. If the people we purchase things from must be morally pure and politically aligned with the buyer's viewpoint, the majority of products available for purchase in the US fail that test. Even "good" businesses that pass the test still must rely on an exploitative and unethical supply chain for their materials and distribution.
Regarding the farmers market though, yeah kinda. If we shouldn't buy goods from Walmart because they are owned by fascists and exploit their workers, why is it okay to buy produce from MAGA farmers using criminally underpaid undocumented migrant labor? The short answer is it's not. The only difference is scale.
I'm somewhat of a hardliner on ethics and morals. In my opinion something becomes unethical and morally wrong if a single person is exploited. I have no interest in measuring inches and degrees of evil.
