Yes, this is the correct Christian teaching. We have a duty to condemn sin both in ourselves and in others. Why? Because sin is death and God is life. If we love our neighbor we will not tolerate his sin. The "you shouldn't judge" libtard false Christians (influenced by jews obviously) are wrong.

This is why the freemasonic (jewish) idolization of individual rights and freedom of speech or libertarian NAP is incompatible with Christianity. "You do what you want, as long as you let me do what I want to do" is jewed up philosophy that appeals to human pride and base desires.
