Cyclopeatron has a wonderful post about the secret double lives D&D players find themselves in. To be out or in the closest, that is the question. No question really - closet.
The similarity with homosexuality is something very confronting. If I struggle to come out about a game/hobby I enjoy, how much harder is it for someone to come really out in something which sadly still matters in society. Maybe we need t-shirts for our mothers' to wear saying "I love my D&D son." or "OSR and proud"
It did make me seek out an article I read in 2008, while I was collecting old modules off eBay but yet to discover the OSR. The article was by the UK Conservative MP the Right Honourable Michael Gove and he outed himself (D&D variety out).
You can read his outing in the Times Newspaper at: http://www.timesonline.co.uk/tol/comment/article3522620.ece
And see his mug shot:
He is still in parliament, which must mean that OSR voters make up a large part of his constituency... I wish him the very best. Maybe you reading now Michael. Well done - you are a braver man than me.
