Yes, but for different reasons… I reasoned it out this way: Dwarves believe that you are first and foremost a Dwarf, and the differences in sexuality or gender simply do not affect their perceptions of each other – because Dwarves of ALL genders and sexualities are strong, clever, broad and stocky, created by and beloved of Mahal.
When it comes to Elves, particularly Elves of the Third Age (as opposed to the hotheads of the Age of Trees/First Age etc), I had these ideas, idk if they’re well put-together, but here we go!
Elves are, as a race, old. They will live forever. FOREVER, barring accidents or war. The greatest natural threat to their life is from growing so old that they literally fade from existence.
so, if you’re going to live forever, what the hell use is it to deny who you are and whom you love? And if that person there is ALSO going to live forever, then what the heck is the point of imposing your beliefs upon their love and life? Elves have seen wars before – HAVE THEY EVER – and they’ve seen inter-Elf violence and civil war, they’ve got very, very, VERY LONG MEMORIES. They’re a dwindling people, too. And Big Stuff is coming, and they know the signs. They’ve seen them before. They have learned.
So, let’s say you are a different gender to the one everybody initially thought you were? Congratulations, we shall have a marvellous garden party, I’ll bring the Dorwinion, you bring the lembas. And nobody will fight, and everyone will be pleased. We’ve got to stick out the next eight millennia together: I’m with you all the way.
