Its not really stolen from Discworld. I mean I could argue it was “stolen” from Myth-adventures as much as it was “stolen” from Discworld.
Pratchett takes the piss on a lot of ‘norms’.
Yes there is a vampire temperance league and there is a side character who is a vampire who talks like that, but it’s just background pretty much.
I agree “old” Trek was woke too. It just blended in better imo. (Especially with Disco, it felt like there was a metaphorical spotlight on the “woke”.)
