Emotional thinking is, above all, dangerous and evil - on a personal level, a national level, and a societal one.
There is not much we can do to change these over-arching social trends. We can, however, choose not to be emotives ourselves, and to avoid dealing with emotive people and engaging with emotive media - and recognizing it when we see it.
Sadly, most folks today cannot distinguish between a logical argument and an emotive one. As the recent Presidential debates illustrate, logical discussion of policy issues puts the plebes to sleep. But a carefully hurled insult triggers the emotional side of our brains.
