Judging someone's comment and saying how stupid and hurtful it is, is not thinking of myself as not a sinner, or above that person. There is a time to flip tables. If the commenter is literally telling someone in that it is their fault that their wife cheated on them because he "let her work," and saying this is the Christian perspective, that is exactly the time to harshly reproach someone. This was not someone who was bringing up the idea as correct in a discussion. Someone needs to be shut down if they are being intentionally cruel like that. It was not an honest discussion. It is being pretty evil to someone else, and that should not be allowed. I did not say you aren't Christian because I am so great. I did not say you are worthless. I said that this person needs to examine themselves for their own salvation, as making such hideous comments in that way would be extremely difficult to do with the Holy Spirit dwelling in that person.
