Hey Volprof let me make it simple for you.  Let's get to the bottom line as far as God is concerned.  Plain and simple homosexuality is a sin.  The wages of sin is death.  Homosexuality is a sin just like other things such as  drunkenness, using the Lord's name in vain, etc.  Further, homosexuality is a sin which is defined both in the New and Old Testament.
Every single person God put on this earth made us predisposed to certain sins.  I can tell you I am not predisposed to homosexuality but I am predisposed to other sins. Yes, I can do certain sins very easily.  See how simple that is?!
Finally, if you are correct in you "educated" secular view and I am wrong then no big issue.  On the other hand, if I am correct you will have a long and unpleasant time thinking I wish I would have listened to that man!  I'm not PC but a unapologetic follower of Jesus Christ.  Love the person but hate the SIN!
It's as simple as going to God with a repentant heart, asking for forgiveness, and asking him to come into your life.  I am an example of how God will forgive sins!  It's that simple but unfortunately some will never understand!
