I know this isn't the point of your comment, and I'll tie it back to CFB, but actually the Lord says to judge others. Christians are supposed to condemn evil (because God hates sin). That verse, judge not lest ye be judged, should be taken in context with the rest of Matthew chapter 7--specifically, verse 5.

For anyone's interest, Other bible verses that say to judge:

John 7:24 - Do not judge by appearances, but judge with right judgment.

1 Timothy 5:20 - As for those who persist in sin, rebuke them in the presence of all, so that the rest may stand in fear.

2 Timothy 4:2 - preach the word; be ready in season and out of season; reprove, rebuke, and exhort, with complete patience and teaching.

Ephesians 5:11 - Take no part in the unfruitful works of darkness, but instead expose them.

(See also: Luke 17:3, Romans 15:14, Titus 2:15, 1 Thessalonians 5:14, etc.) There are nuances, and I'm more than willing to nuance those out in a pm.

So anyways, TL;DR, we should absolutely be calling this out. Unacceptable behavior.
