Look, PETA is not exactly the model organization they think they are. Actually they have plenty of issues and hypocrisy with their own messages and IMO are by no means a credible or reliable source. BUT, credit where credit's due, their shitpost that everyone hated got more discussion from both sides on the realities of the meat industry than any whistleblower or researcher publishing a paper on the conditions of industrialized meat farming, its environmental and climate implications. More engagement from this than pretty much any measured response, analysis, or criticism of the meat industry or the ethics of eating meat that has ever come out. This thread is an example of that.
That might say more about the nature of internet culture and what people will actually respond to and engage with than anything else. Obviously in an ideal world everyone will engage way more with those whistleblower and scientific researcher findings and organizations like PETA wouldn't even exist, and it would be the measured responses that will be the things triggering discussion on subjects like plant-based meat and veganism, probably a much more level headed discussion since that tend to be more dependent on the context of the discussion than the subject itself, and we really should be working toward that. But, I think that's still a silver lining because we absolutely need to be having these discussions.
