Don't know what to say that hasn't already been covered in five pages of comments, but don't date people who denigrate your hobbies. There's no "age cutoff" for enjoying the things you enjoy. You don't just stop enjoying things after a certain arbitrary age threshold.
The old view of adulthood as being a time of constant misery, struggle, and hardship, in which every moment of enjoyment you manage to claw from it is a moment stolen from the future, which will be replaced by further misery, is fucking stupid. Do what makes you happy, and ditch the Karens.
