It seems reasonable and right to be "respectful non-discriminatory" to homosexuals - just the same way alcoholics, drug addicts, slanderers, and gossipers should be respected.
That is not to say however, that homosexual acts are to be condoned any more than drunkenness and gossip are to be condoned.
It should be absolutely, crystal clear that we love and welcome you - sinners - but your actions are destroying you, and harming those you love. Repent - daily if necessary - and be saved...
Believe and repent each and every day!
