I have a little problem joining in with the stone throwing. To begin with I'm not sure what correct sex is. I grew up in the catholic religion and it was male on top, to completion and only to conceive an offspring no birth control.
Guess when it comes to sex most you guys are a little shaky from where I stand :-O
One of the things people miss about the stone-throwing parable is that the people standing around holding the stones were preachers involved in a plot to kill an innocent man. One is hardly in a similar position when one says, "Homosexuality is wrong." I could sit here and list a whole host of things I've done that are wrong...the stone thrower is not the one who believes that sin is sin, the stone thrower is the one who believes his or her sin is OK, or that he or she not a sinner, or that someone else is a "real sinner" and he or she is not.
Another thing people miss is that Jesus said "Go, and sin no more."
