One such principle is perhaps about how to prevent bringing our emotions to bear on a situation that have less to do with the parties involved than with our own circumstances. It seems that no one is helped if we articulate our own opinions in a way that reflect mainly our own perspective rather than that of the parties involved. Consequently, perhaps the best we can hope for is to be conscious of how anger at perceived injustices mainly answer to the needs of our own psyche. Consequently, if our anger does little to contribute to solutions, perhaps we should refrain from anything that may inflame the conflict between those involved in a dispute.
However, overall, I suspect, there is little to be gained from weighing into a debate that matters to us only through our emotive responses. In a sense, all we do then is to speak to our own emotional needs. That does not sound like a good guide in navigating the complexities of political problems.
