Also, alternative explanation of the lizard people thing: http://esr.ibiblio.org/?p=8600
Yeah, no. That doesn't fly.
There's a massive difference between, say, "the fact that I am a person of European descent living in upstate NY is only possible because of the genocide of and racism against generations of Native Americans; therefore, my entire existence is predicated on structural racism" and "many, many groups have vilified Jewish people for centuries for a variety of reasons (that are out of scope of this discussion); that vilification has led to ostracism and genocide on numerous occasions and still does to this day, frequently based entirely on completely false stereotypes; the propagation of those stereotypes still to this day leads real people to choose to ostracize and murder Jewish people; "lizard people who rule the world" is one of those stereotypes, and participating in its propagation does actual, measurable harm to Jewish people."
I’m curious how far this stretches. Do you claim that “They Live” is antisemitic?
You can just as easily ask "why was there a rise of right-wing nationalist and fascist sentiment throughout the Western world in the mid-to-late 2010s?" There's no grand conspiracy to any of it, and looking for one is likely to lead you down exactly the road that far too many conspiracy theorists have gone recently.
And, um, closely related, be aware that the "lizard people rule the world" thing isn't just a funny joke. It's deeply and inextricably rooted in a raft of antisemitic tropes, slurs, and propaganda going back...I forget exactly how long, but at least many decades. In fact, in general, when you encounter any conspiracy theory that posits a shadowy group of people secretly ruling the world, the chances are nearly 100% that you can trace it back to a version where that "shadowy group" is explicitly Jews. This is a big part of why conspiracy theorists have a tendency to find themselves in a pipeline to fascism.
