Haha, legal gay marriage might be controversial (in some places), but the existence of homosexuality is pretty well settled at this point, I think.
It doesn't matter, it's a lightning rod for trolling or abusive posting.
Did you
look at those threads linked back from where you quoted? Half of them end in Toady saying "This thread has been reported several dozen times per day, so it's locked. I banned so-and-so."
And those are the threads that were merely locked - there are more that had so much crap in them that they were deleted (and more people banned).
So, again, don't bring the topic up in this thread, as it tends to attract the sort of people who make inflammatory statements who only wind up getting banned.
I don't see why Toady would do it, I'd rather have him spend his time making the game than adding flavor for people.
As if the game isn't full of flavor already... It's not like it had to be dwarves and elves and goblins.
It'll probably go in when Toady has done enough personality rewrites to make any sort of romance actually possible. And yes, I'd actually like to see personality advances worked on to the point where dwarves have goals and desires and act upon them rather than being happy automatons until the day their happiness meter hits 0 and they go into self-destruct rampage mode.
