Yes, because how dare someone have a non-conventional hobby. Furthermore, how dare they be encouraged to discuss what makes them happy with other people.
As someone who would cheerfully discuss the command pattern, the difference between a hypen, an en- and a em-dash, or conventions in writing audio description scripts, I don't begrudge anyone their non-convential hobby. I'm not quite sure how you even reached that conclusion.
Funny enough, people don't ask me about those things, and I understand because while I'm sure I would be entertained to discuss these, it would be psychosis-inducingly dull for almost anyone else.
Nobody wants to listen to me talk about esoteric subjects; and I sure don't want another repeat of, for example, the time someone labouriously and very, very slowly "explained" the plot of some tedious Game of Thrones thing in some unstructured meandering format that was crushingly and grindingly dull. Absolutely excruciating.
So the idea of someone asking about that is hilarious in a very, very sick way.
