To me the issue is this..
Homosexuality is currently one of the "politically correct" (or maybe better worded "Christianly Correct") sins to be against.
If you step back and look objectively at how the Church has been involved in various moral/political issues, even over the past century, you see that about every 10-20 years there is a new "hot topic" that everyone's upset about. Then, that fad passes, and there's a new 'cause' that everyone is in an uproar about. At different times it has been prohibition, abortion, bigamy... and now the current "hot topic" is homosexuality.
The truth of the matter is that people have been committing sin of all kinds the entire time. And all sin is just as wrong, whether it's the one being focused on or not. But when was the last time you saw a church group lined up to protest an all-you-can-eat buffet? Gluttony is sin, is it not? It's just not as "sensational" a sin. I always find it amazing to me that an overweight minister will be in the pulpit preaching about the sin of homosexuality (or whatever the hot topic may be that week)-- and wonder if he realizes he is in just as much sin.
I'm not saying that we should be "soft" on sin... in fact, if you read my posts here, I've actually been harder on sin than most. I'm just saying we need to recognize all sin for what it is and not just pick and choose one or two to make a fuss over.
