Jesus also spoke about being Lukewarm. You can't agree with or be indifferent to a sinful lifestyle (whatever it is) and be pleasing to christ.
Why is it everybody can remember " judge not lest you be judged" but not much else. Christians are supposed to let their brother or sister know if there is sin in their life. In order to do this there must be judgment of what's is right or wrong according to the word. We all will be judged by the word in the end and there will be no arguments or appeals.
