If they had kept their disease and behavior private and did not seek to recruit then I'd have no problem with them living as they wish. The problem is that they are a hazard not only to themselves (see Scripters disease data) but to society as a whole (see the molestation,crime,drugs etc data) and they refuse to keep their perverse behavior private.
Of course the humane thing is to get them cured but if they won't seek the cure then they will bear the responsibility for it. Can't force someone to get better, you can only quarantine them away from the healthy population
I disagree with you on specifics regarding homosexuality, as to:
1. homosexuality is a disease with a definite cure - I take it as a way that someone is, with a limited degree of changeability
2. what constitutes public or private behavior
3. what constitutes recruiting
However, I don't entirely blame you for being intolerant on many counts.

Human beings must be responsible in any case for what they are and what they do.
...you can only quarantine them away from the healthy population
I'm afraid you've once again stepped way out of line, in my opinion.
