related, especially because of the 
stench that wafts off of "the problem is both sides are too extreme" Enlightened Centrists that already showed up here, and few things get them more defensive and tribalistic than vegans existing, let alone stating (correctly) the cost and consequences of industrialized meat production.
I’ll add to my own bet: I bet that it will start because of the content warning policy for meat-related food posts and some DAE LE EPIC BACON bazinga will get mad about content warnings existing for their treats.
