On just about any subject you will find seemingly intelligent people on opposite sides of the issue. Each side will provide evidence that contradicts the other. Most of the time, a person's choice of sides is completely arbitrary, depending on what demographic to which they belong.
So who to believe? Unfortunately, most people will not even consider asking this question of themselves. They simply march lock-step in time with their chosen propaganda machine and remain blissfully ignorant - content with life as they know it. It is a sad commentary on Western Civilization that logical thinking is despised. From the time we were in grade school, anyone displaying the ability to think on a level even slightly above the average, they begin to draw the ire of fellow students and the epithets begin. Nerd, dweeb, dork, geek, etc. those lucky enough to have some athletic ability can redeem themselves by masquerading as a jock. Those who lack the social skills to overcome being the object of scorn and derision become pariahs. In addition, in certain parts of the country, in certain demographic groups, there are those who accuse their peers of being race traitors if they attempt an academic pathway in life.
Let's face it: being smart is intimidating for a lot of people. And there are a lot of smart people that enjoy lording it over other people. They mention the results on the last IQ test they took. They remember what their SAT scores were. They announce that they belong to Mensa. Anyone bragging about what they can do better than you is irritating, but smart people bragging about how smart they are is perhaps the most irritating of all. No one likes feeling inferior. When one's inferiority is pointed out to them, either directly or indirectly, they feel threatened. A usual first reaction is anger and frustration, and sometimes to return the perceived threat with violence.
The same thing happens when seemingly intelligent people find themselves on opposing sides. Rarely does logical discussion ensue (at least on television). Usually things devolve quickly into a shouting match or ad hominem attacks. The issue itself is drowned in a muddy river of insults and non sequiturs.
