If you get a group of t-girls together, in the UK at least, you won't have to wait long before the subject of militaria crops up. It's part of the stereotype.
Mrs. J and I spent Sunday lunchtime in a very nice pub in Wiltshire with a group of t-girls, four of us and two partners. I think I may have stumbled on another stereotypical facet of the Average British T-girl, amateur radio. Around the table we had a G7, a G1 and a G0. I have to admit to letting my licence lapse a few years ago so I was unable to contribute much.
It's getting more and more as though I should be looking at my acquaintances and asking "Would the non-trans ones please stand up"?
