"Right Speech means abstention, abstention from four things. One, from telling lies; two, from backbiting and slander and talk that may bring about hatred, enmity, disunity, and disharmony among individuals or groups of people." That covers a lot. "Three, from harsh, rude, impolite, malicious, and abusive language. And four, from idle, useless, and foolish babble, and gossip."
