OK, NolittleBuddahs, I accept you didn't mean "lifestyle" the way I thought you did.
We agree about the issue of trivialisation at least, it seems.
I'm really, sincerely, surprised to see you say that you don't in fact think it's reasonable for people to have to [dissemble about their family lives]. You've said several things to the effect that people should be cautious about mentioning anything touching on gay relationships; if I'm gay, and I have to [consider] how difficult the subject of homosexuality can be for some people to hear about and discuss and I have to be careful about talking about Civil Partnership because of how divisive a subject it can be, then how on Earth do I participate in a workplace conversation about (to take as an example a conversation in which I've taken part more than once, in more than one workplace) wedding plans and dreams? I'm not allowed to play the "I'm gay so don't comment on my lifestyle" card, so if I talk about my real plans or hopes, I have to accept that my colleagues might tell me that I shouldn't even be in the couple in the first place. So do I lie? Do I say little, smile and nod? My straight colleagues can be quite straightforward here, but I can't. How can I not end up excluded?
I apologise for the extensive and probably tedious quotes; I am puzzled and frustrated by people (not just Nolittle) not seeing how not allowing a particular minority to speak freely about their family lives, in a way that's par for the course for everyone else, is the same as excluding them and discriminating against them. I'm trying, no doubt inadequately, to make the link clear.
I should probably say that people who adhere to a religion should have indeed, do have, in part thanks to the EA exactly the same right to join in conversations about family life, which might, of course, include religious practice, without worrying that people will challenge their right to those practices.
Anyway, I'm conscious of derailing farandaway's thread, so I won't reply further unless someone wants to take the discussion to a new thread somewhere else, in which case I might join them there subject to the constraints of the working week.
