If homosexuality was something that was harmful to the individual or the society, then one could say it would warrant looking for a cure.
I do agree with the opening post that after leaving the JWs, we have to make up our minds on things that was a given before. We have to think things through with a new set of glasses, as it were.
-Some claim that evolution 'dictates' that homosexuality is wrong, because it is an evolutionary dead-end. To some degree this is correct, however evolution is not Evolution; there is no intelligent guiding force there to decide what goes and doesn't go. If homosexuality had been 'against' evolution, it would have disappeared long ago. But obviously - being gay is not an evolutionary advantage; it's not something that is naturally selected for (for that to happen, it would have had to be in a scenario where most heterosexuals died from a disease only lethal to them, and gay men had children with lesbians). But then again it's not an inherited trait either it seems - it just occurs here and there for no apparent reason (as of yet), and in fairly small numbers compared to the general, heterosexual population.
-From a (biblical) God/religion point of view, I guess people there think it's wrong because it's "using your body" in a way that God didn't intend when he created humans as man/woman (and obviously the couple of scriptures they usually quote). If so, it would be very unfair to the gay people that they would have to fight this 'problem' all their lives, while for straight people it would (eventually, in marriage) be a source of pleasure and would be exactly what was expected of them. OK - so life in general isn't fair - but... God in his almighty, future-seeing wisdom should have at least prevented 'gay' from ever occurring in that case. It's not a sin to have a disease, but being gay is it seems, so it should have been prevented from the start in that case. Strictly speaking, sex was created solely in order to have children (what other 'God given' intention would it have?), so in that sense, straight couples are doing a lot of 'unnatural' things as well.
As long as it's true that people fall in love with and are attracted to others of the same sex (and it's mutual and consensual, of course), I don't see anything wrong with it.
I think that's my current view on it (still in the process of forming/changing my own ethical guidelines).
