“Do not have sexual relations with a man as one does with a woman; that is detestable” -—Leviticus 18:22 (TNIV).
“Because of this, God gave them over to shameful lusts. Even their women exchanged natural sexual relations for unnatural ones. In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed shameful acts with other men, and received in themselves the due penalty for their error” -—Romans 1:26-27 (TNIV).
These people obviously haven’t read their Bibles.....
You said — “These people obviously haven’t read their Bibles.....”
Of course they have... They’re simply trying to deceive. They know very well but are the *very ones* who are described in that portion of Romans that I quoted...
Actually, they probably have read "their" bibles...they got rid of everything they didn't like, which, I'm sure, includes the verses you cited. But they haven't been reading God's Bible.
