"Judge not, and ye shall not be judged: condemn not, and ye shall not be condemned: forgive, and ye shall be forgiven" - Luke 6:37
"For what have I to do with judging those outside? Is it not those who are inside that you are to judge? God will judge those outside. "Drive out the wicked person from among you." - Corinthians 1:12-13 (Curtesy of Dave Tesla)
One can justify just about anything from Biblical verses. The verses on chooses for any particular situation tell far more about the individual making the choices than about God's intentions.
The idea is balance the scriptures to match God's overall intentions, instead of pulling them out of context for our own purposes.
And it isn't too difficult to see who is seeking God's true message and who is not if one has a fair knowledge of the Bible.
