So went the childhood chant.
I have to call attention to an excellent comment by one david g.
Yes Loshon hara is forbidden but it is not a ritualistic prohibition. It is meant to make us better so that we dont see the negative in others. The person that sees the issur as a ritual will not talk Loshon Haro but still look down on every other person that is not exactly like him. Yotzo schoro behefsedo.
