Politics is like any addiction ...... it starts out your compelling friend, and ends up your enemy ;-) I sympathize with others desire to vent, as it is a compelling sport that has a pleasing physiological impact by arousing adrenaline and flooding the body/brain with various exhilirating endorphins.
Unfortunately logic and argument seldom seem to convert anyone to one's own viewpoint, so the old addage fits:
Fools argue, wise men discuss.
