The comment is common. We have all seen it. sometimes do it. Some always do it. I can't help it sometimes and do it. So, what comment? It is more of a type of comment and it's blow-back. Let's say "poo" begins by throwing a general insult to half the population, followed up with a personal insult of the immediate preceding commenter. Then "poo" explains why everything THEY say is pure goodness, and the way everyone should think. A typical message might be something like your whole political side is evil, racist, blah, blah...Then perhaps an attempt to justify it with some week anecdotal evidence is added. But wait. Lets look at the messenger. His opinion is now entangled with his ego, If any part of his argument is proven wrong, every part of his debate is lost. Simply put, HE HIMSELF has put his own self in a small box with no wiggle room. No one else has done what he has done to himself. So now he has a choice cut and run, or ramp up the insults. On the other hand when you allow others to at least be heard, they will take an immediate liking to you. File this under advice I intellectually understand, and am trying to apply....usually....O.K, sometimes.
