“Is it also Ok to speak Lashon Harah about people who molest? Abuse, Cheat in business or taxes or other averiahs”
“That argument cuts both ways – are you (or the others here) makpid to never criticize or talk about all those whom you just mentioned?”
I think his point was the other way around. That he has been accused of speaking LH by possibly some of the same people who are claiming here that this is not LH. So he is saying that they should either acknowledge that this is LH or not accuse him of speaking LH.
However, I think the response to that would be that the two types of scenarios are not the same. The equivalent example would be someone who molests in public and claims that it is halachically permissible.
