Looks like someone has been putting all their own prejudices on to us ladies of a certain age!
Honestly, you get to a certain age and you realise (if you didn't before) that gay people are a completely normal section of the population and it's an insult to think that middle aged and older women are all of a twitter just because the person on stage is gay. Come on!
Can you imagine? We're all enjoying the performance and then all get the info - "oo, guess what, he's gay" - massive stampede for the exit!
As someone else said *falls about laughing*
