It’s happening there because those are realms where conservative male fans are willing to do unpaid scutwork for ideological reasons, since conservative women are no longer allowed the leisure to conduct the culture wars.
Unpaid scutwork for ideology is not exclusively female, but women do tend towards a genuine preference for licking envelopes and composing form letter templates as compared to men. I am not at all the first to point out the female preference for dull desk work, but it’s interesting when men do decide to provide a bunch of unpaid labor for a movement.
This is one of many reasons why I get all strident and repetitive about the cult of drudgery for housewives. It’s not bad, guys, if there’s a class of women with leisure and free time, who are supported by their husbands. Most of those women were not feminists or proto-feminists, contrary to the bizarre conservative narrative that “overly leisured housewives” are the source of all modern woe. Leisured housewives are the women who provided the unpaid labor that supported so much that conservatives claim to adore, like functional public schools, social institutions, community events, parishes and other church infrastructure.
And it is very telling that you can only get leisured men to provide unpaid labor when it’s weird nerd hobbies.
