I'm about as un-homophobic as a straightish boy can be - I have lived for years happily with a lesbian activist couple, for example - but I still found the 'do they have to shove it our faces' aspect annoying, because it was clumsy and obvious and distracting in a show that is supposed to be more about SF adventure, and sometimes (particularly the notorious Owen bit in the first episode) just done really badly. I am pretty sure my dislike of the shows treatment of sexuality is about quality of writing not homophobia (I've actually tended to like the more episodes that feature sex front and centre, like the second last, far more than the gratuitous added scenes).
