it depends... if I walk into a game were people don't wish to discuss my personal life (for any reason, maybe poltical, maybe religus, maybe sexual) and I inisit on not only making it a point in game, but forcing it... no matter what it is, is still being a jerk...
I'm... not sure of that.
I've been playing D&D for >30 years now, and I've seen a whole lot of people play a whole lot of characters. And guys mention having a girlfriend or wife, and it is
never an issue. Not once, ever. But if a guy mentions a boyfriend or husband, suddenly it's an "issue", and they're "making it a point in game". And that's sort of unfair and unbalanced, and no, I don't think it's "being a jerk" to refuse to accept that bias.
in my above examples if your "Gay Player" wants to sit down with my brother in law, my neice, my nephew and one of my other friends and play D&D... he or she needs to respect that we don't care what he does as long as he keeps it out of game, and out of ear shot of my two small kids... I would feel no different if a "Straight Player" insisted on bringing sex and gender into the game...
I simply don't believe you. Because the thing that gay people do that gets accused of "bringing sex and gender into the game" is nothing more than mentioning their relationships in passing. And I don't believe for a minute that you'd even consciously
notice if a straight male player referred to his "wife", or referred to kids (which would sort of imply sex).
And that's why this is a big problem; because we take straight people for granted so much that mentions of a wife or girlfriend or kids
don't even sound like mentioning sexuality to us. So people say "oh, I'd be upset if anyone brought it up", but the fact is, if you have precisely parallel behaviors, there are a whole lot of behaviors that get gay people yelled at and don't even get noticed when straight people do them.
That's why this is an issue that justifies some kind of attention or discussion in the community; because people will drive other people away with bigoted double standards
and have no awareness that they're doing so.
