Keep your version of 'God's law' for your own denomination and congregation, thank yoy; the Crusades ended centuries ago.
''My version''? There's really only one way to interpret this:
''Thou shalt not lie with mankind, as with womankind: it is abomination.'' - Leviticus 18:22
This law may be from the Old Testament, but it still applies today because it is a moral law, as opposed to a ceremonial law (such as the prohibition on eating pork, for example).
None of the old testament is applicable to Christians today, when Jesus died on the cross it ended the laws of the old testament.
"For Christ is the end of the law for righteousness to everyone who believes." - Romans 10:4
"by abolishing the law of commandments expressed in ordinances, that he might create in himself one new man in place of the two, so making peace," - Ephesians 2:15
"Now before faith came, we were held captive under the law, imprisoned until the coming faith would be revealed. 24 So then, the law was our guardian until Christ came, tin order that we might be justified by faith. 25 But now that faith has come, we are no longer under a guardian," - Galatians 3:23-25
Don't use the bible to justify your bigotry.
