Many years ago, when I was a new believer and told someone they were wrong about something according to the Bible, a woman told me I shouldn't tell people they're wrong, while she was telling me I was wrong for telling people they were wrong.
Those who say we should not judge cannot be consistent. If they were consistent, then they would not judge us about anything we say and do.
It would be irrational to think that we could go through life without judging whether or not something or someone was good or bad.
Those who only like to judge others as good are forgetting that declaring someone is good is also judging.
God declared that we should judge righteously according to His principles and commands, not according to our own.
