Matthew 7:1 (“Judge not, that you may not be judged”) was, by the context of the subsequent verses, clearly an admonition to not be hypocritical in judging.  The Bible, however, clearly does emphasize that we must judge – avoiding evildoers, etc.  John 7:24 – “Judge not according to the appearance, but judge just judgment.”  Matthew 18:15-17 – “If your brother sins against you, go and tell him his fault…”.  James 5:20 – “He must know that he who causeth a sinner to be converted from the error of his way, shall save his soul from death…”.  2 Timothy 4:2 – “Preach the word: be instant in season, out of season: reprove, entreat, rebuke in all patience and doctrine.”   And the Bible (New Testament) is most clear about the grave sin of homosexuality:  Romans 1:27, 1 Corinthians 6:9-10, and 1 Timothy 1:9-10, among other citations.
