When I was teaching one of the kids' fathers got outed (he was also the chairman of the govenors) and it was in a small village (2000 people).
It caused quite a bit of discussion, at one stage I overheard it and one of the kids said "oh don't worry sir we're not talking about you"

Mainly the sentiment was sympathy for the daughter (14) and how they would feel if it was their dad. Anyway it was soon yesterdays news. (BTW this was the eighties)
But TBH it is a big deal and one of the reasons I choose to stay stealth is that I know I couldn't handle it well. My daughter now 34 couldn't care less, but she was a nightmare as a teenager and it probably would have been a big deal to her, but I'm not sure in what way it would have affected her.
