Many Christian men and women struggle with homosexual attractions. In most cases that I know of, all the confessing and renouncing in the world does nothing to change their sexual orientation.
As you're well aware, I don't share your conviction that the very few verses that speak out against male-male non-consensual sex (in Leviticus) or arsenokoites (in Corinthians) constitute a universal condemnation of all forms of homosexuality or homosexual activity. That being the case, I don't share your belief that homosexual orientation consitutes an attraction to something that is ungodly, nor that is any more likely to lead to sinful lust than heterosexual orientation is.
Again, I can't really agree with your view of things here. To be honest, even when I did share your belief that homosexual activity was sinful, I wouldn't really have felt that it was any business of mine what people get up to in their bedrooms, and I'm not sure that either homosexual attraction nor homosexual activity can be considered dangerous, not with all the genuinely terrible things going on in the world today (compared to war and murder and rape and child abuse and destruction of the environment, two consenting adults having sex in their bedrooms, regardless of their genders, really seems pretty trivial).
Again, I really can't agree with what you're saying about homosexual attraction being a "burden". Although in fairness, different people react to their sexual orientation in different ways, and I can well understand how someone brought up in an environment of being surrounded by people who told him or her that "homosexuality is a sin" would regard it as a burden if they realised they were gay. Someone not brought up with those preconception would probably not share that feeling of it being "a burden".
Also, Christians who are homosexual do live for Him with all they've got. I really wish you'd understand that.
