Personally, I think pornography is wrong and degrading to women, and I don't like people who support it.
Whatever two adults want to do with each other is none of your business. If one adult wants to be paid money to pose for nude photographs and another adult wants to pay money to photograph someone nude, it's none of your damned business. Why would you think that what one woman does reflects on all women? They are individuals.
Bitcoin having things like "bitcoin porn" is not going to make it look better in the eyes of the general public.
So what? Anyone that can't tell the difference between a medium of exchange and the services that accept that medium of exchange, probably couldn't figure out how to use Bitcoin anyways.
