The verse "Judge Not" is about hypocrisy not about judging.

Christ followers are to excel at judging.

Jesus said in Matthew 7 "Judge Not," yet secularists seem to think they are exempt.  What Jesus said in context is often discarded.

Jesus said in John 7 "Judge with Righteous Judgment," yet secularists seem to think they can force their moral beliefs on the rest of us, but would be outraged if religious people forced their beliefs on them.
