It's always amusing when atheists, liberals and muzzies attempt to lecture to Christians. The Bible does not forbid judgement. It cautions against it. It also encourages Christians to exercise some judgement "Mtt 18. A good tree cannot produce bad fruit, nor can a bad tree produce good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 So then, you will 1know them by their fruits."
