The Church will be blamed for many things--- I'm sure Satan is enjoying this very much.
As for the gay people committing suicide, I don't know of any church (personally) that teaches that a gay person should kill himself/herself. But the church DOES have the responsibility to teach the faith correctly and homosexuality is a sin, just as pre-martial sex, stealing, and murder are sins. The people who are killing themselves are to blame--- harsh, I know, but as a person who has dealt with depression, I've been down the suicide road and you ALWAYS have a choice. It's truly a shame that these people did not repent of their sins and come to know Jesus in their short lives--- my heart breaks for them, but they didn't have to kill themselves because of the pain they felt from being told that their sexual preference was wrong.
