The Bible clearly defines homossexuality as worse than fornication. It is so because it is one step further into a mistaken perception of reality than fornication (I use "perception" here meaning more than just information about the world, but as existencial experience of it).
The fornicator cannot see - or has fought against it - that since each soul is unique, there is a unique match for each (even if the unique match is a celibate life, even for straights), and that there is a real somehow physical connection with every person we have sex with - you become one flesh. Because this is somehow metaphysical, it is indeed difficult for most to even think there may be things like these.
In homossexuality, one goes against a very physical and visible reality, and in their own bodies. It requires a more conscious decision to deny reality to indulge in it.
The way I deal with this is to remember that although I don't have this particular temptation, I do have others that are not less impulsive or physical, like gluttony. Do I eat things that I know are unhealthy, thus, somehow accepting it may be a form of slow suicide which I accept at that moment only to indulge in them? Sometimes yes, and suicide is a far worse sin than homossexuality. I know it is *very* difficult in our time and age, to get rid of all the subconcious cultural garbage that says "if you don't indulge in your passions you're not truly living. To be alive is to pursue what makes you happy and feel good". I know that, I feel that in my own temptations, so I am able to have empathy to my friends who happened to be victims of that particular kind of sin.
The problem is, in my view, that no one pretends that glutony is not a sin. Or lust. Or fornication. Even if you fall and do it, you are "awake" enough in understanding that you are sinning, and that's good, because you can repent. Like a monk once said, "we fall, and get up, we fall and we get up, that's the Christian life". With homossexuality people are being told there is nothing wrong in it, that repenting would be some kind of self-aggression, which it obviously is not. They're mislead to fall and stay there. With friends or colleagues who have clearly made a decision to live up their impulses, I must respect their adult decision. But if they ever ask me what I think, or what the Church teaches about that, I try to explain as softly as possible, but also in truth. But only if they ask.
