GNU Taler is not your enemy. It may not solve every problem you’d like it to, but its adoption by the masses would be a vast improvement in privacy compared to the current state of commerce in every country where it has the slightest chance of happening any time soon.
Maybe Gygax said genuinely sexist things about “women’s lib” when he got defensive about the topic, but if the only example you can find of that being reflected in D&D is that one time they added a male dragon who was good and a female dragon who was evil it seems difficult to justify writing that many words about it.
