Personally speaking, it would depend on how well a given LGBT character is written.

If the only interesting thing about a character is the fact that they are LGBT then, to me, that's some bad writing as it makes them a one-dimensional cardboard cutout.

If the character is LGBT but is well-rounded then I am perfectly OK with that :)

Speaking of LGBT, there is a game we hope to release that will show how to properly write LGBT characters without being hamfisted about it :) I hope it will be well received here :)
