This is so far from correct it isn't funny. Nor do I understand how Jesus' teachings play into it, since most of his teachings would not meet your standard of morally wrong. Unless you have a moral objection to forgiveness and love, not striking out at those who offend you, or even forgiving your murderers during the act of killing you.
Do not confuse the men who espouse religious teachings with the actual religious roots. And even those very flawed men have changed in 2000 years. The church does not lead crusades, torture and death is not used against those accused of heresay, witches don't burn at stakes, Catholics allow divorce, Martin Luther created a whole subset of Christians with the notion of change, sermons are no longer exclucively spoken in Latin, astronomy is recognized, and some groups even allow gay bishops and have gay-friendly churches.
The problem is the people, not the religion.
Yes, every time I commit a sexually immoral act I sneer at Heaven and show God my pale butt. [/sarcasm]
Do you sin because God told you not to? Or do you get caught up in a sinful act and then realize you were inappropriate after it is too late?
The only people I know of who perform sinful acts purely because it is a sinful act do it to offend judgmental religious people.
Now, I have a question for you. If an openly gay couple came into your church and wanted to become members would you welcome them with open arms and treat them the same way you would any straight couple?
