Lashon hara

Learned this concept by reading the Wikipedia entry: Lashon hara "is the halakhic term for speech about a person or persons that is negative or harmful to them, even though it is true.  It is speech that damages the person(s) that are talked about either emotionally or financially, or lowers them in the estimation of others."

Helpful speech isn't that complex, isn't just confined to one spiritual tradition or sect. Still, for me it's cool to find specific terms in other cultures that express this idea as a special idea. 

I read the term as someone was trying to shut down conversation about the neighborhood on Facebook, which might be controlling, and preachy, but it is an interesting concept in terms of right speech.

The fellow on FB saw social media in a way as unskillful. I don't see that as true.
