I already answered this, but since you seem to have a terrible case of amnesia, here is the answer again:
you’re spreading false information (your “beliefs”) as fact which could be harmful to others if they’re foolish enough to believe you. I don’t have to gain something in return just to do the right thing by posting the correct information in response. Life isn’t some zero-sum game where I have to be motivated by personal gain simply to do the right thing or because your feelings got hurt.
