Hi friend, I propose you try an experiment: post a small handful of anonymous comments on the Internet, try to make them benign as possible but casually slip in an acknowledgement that you are vegan. Something along the lines of “God that recipe looks amazing, but I think I might swap out the beef broth for veggie broth as I am vegan” like I said the point of this experiment is to say something completely as benign and inoffensive as possible.
Once you post sit back and wait for the responses to roll in. You will likely find that while not every time, it is incredibly common for people to send you pictures of bacon, and an abundant of angry responses to the mere offhand mention of the word.
I sincerely wish it was a straw man fallacy, but it unfortunately is a exceedingly common response to the word.
