I posted this a few days ago on Twitter, and it has exploded to a truly unexpected and overwhelming degree, which has led to several days of amazing conversations and someone messaged me here to ask if I would post it on Tumblr, which I probably should have done much earlier except that I always forget I have a Tumblr. Anyway, here it is, though I also encourage anyone with Twitter to go check out the original thread, as the replies have become a goldmine of further research, dialogue and fact-checking.
All the sources I cited in the thread are linked below!
