SS, follow your own reference just a little bit further, to understand what Jesus meant when He said that...
Luke 6:39-42.... if you're going to try to help others out of their own sinful ways, you'd better be pointing fingers at yourself first... or others will RIGHTLY be judging your behavior as well! Get your own house in order, and don't be haughty and prideful that you're "better" than the other fellow. But that in NO way means that we shouldn't "judge" people's behavior according to the Word of God, and call a spade a spade, when it becomes a public sin.
Right after the passage that you quote, Jesus himself goes on to "judge" people for not listening to His Word, but then still trying to claim Him as Lord... Luke 6:46... "But why do you call Me "Lord, Lord", and not do the things which I say?... vs. 49, "He who heard and did nothing is like a man who built a house on the earth without a foundation, against which the stream beat vehemently; and immediately it fell. And the ruin of that house was great." Why does God himself call on us to stand up for His Word, and against sin, if we are NEVER to judge? Didn't Nathan call out David for his adultery and murder... "You are the man"....
You know what God says about homosexuality... "vile passions, dishonoring their bodies among themselves, women exchanged the NATURAL use for what is AGAINST NATURE, likewise also men leaving the NATURAL use of the woman, burned in their lust for one another, men with men committing what is SHAMEFUL,"................................... "Who, knowing the righteous judgment of God, that those who practice such things are deserving of death, not only do the same, but also approve of those who practice them."
SS, YOU are "approving of those who practice them", by NOT calling it sin, and by not calling those who do it to repentance. YOU are "leaving them in their sin, and allowing them to think that such behavior is "OK" with you, and with God. How is that "loving your neighbor"? And God will hold YOU accountable for your lack of love, and your unwillingness to "care what they do", even though you KNOW that God has declared it an abomination.
