We can all agree that the Bible instructs the homosexual to repent and to not give any justification for homosexuality, or for the groups and political movements that openly flaunt and promote this sin as anything but an abomination.
If a person continues to ignore the Bible (after being corrected) and continues to give agreement, aid or comfort to those who openly promote the abomination of homosexuality, they should be confronted and ultimately shunned until they clearly repent.
What would Jesus have done?
