Speaking as a gay (bisexual) man, I think it'd be great to have gay characters in Trek, but don't shove it in my face. Make it subtle as if it were, I don't know, normal.
Doctor Who has a tendency of making a good deal of it's characters gay for no reason at all.
As a pansexual man, I agree. It has to be subtle in the universe or the utopia we've created will show very little progress from today to then. Don't pander to me, just make it part of the mosaic.
