Ahhh, I see. Yeah, I've definitely seen the "but you're ignoring the Dark Ages!!" style posts—less often, but probably because I'm also on Twitter and the dragon iteration is particularly prominent there.

I do get the selective realism argument (or rather, """realism""")—it's just an issue that isn't well-suited to analogies. I do suspect that a lot of the people making it may not realize that the people they're arguing with are factually wrong all the way down, and that's where the implicit concession comes from.

And yeah, that. That too!

Three cheers for Team No Concessions! :)
