So what is the motivation for these people? What links them together with so much intolerance towards Obama? Well, it doesn't take much effort to notice that nearly all the active members are also part of some Christian group on Facebook as well. Many are so polarized against Obama based on things such as abortion, which is a stupid reason. If you actually look, not a single major political figure has even attempted to overturn Roe v. Wade. It's all a campaign polarizing argument, and never has any substance. Abortion isn't going to be banned, get over it. Another topic is Stem Cell Research, which most people who are against have no real clue what it even is, or what it's potential is. They just know they're against it, because some figure (either political or religious) said they were supposed to be. Stem Cell research has amazing potential and could be the next great breakthrough in biological science or medicine. Of course, it's hard to convince people who refuse to accept Evolution that science/biology is a good thing.
I'm amazed that after the last 2 voting cycles of Republicans getting their asses kicked, that the Right & Evangelicals are hitching their wagons together. It's obviously failing. More of America is atheist or agnostic or non-practicing every year. This isn't some atheistic recruiting process, or some great evil corrupting minds, as most of the nutjobs would have you believe. It's a natural progression away from a Religion. If you think about it, the world has been dominated by different religions over and over, they keep getting debased and a new one takes it's place. However, in this cycle, science has given us something other than the supernatural to look at and many people are seeing how ridiculous it is to believe in fairy tales and base your entire existence and life upon them.
Some, however, refuse to be a part of the movement towards modernism, free thought, & realism. These are the idiots who comprise the very vocal portions of these Facebook groups. I'm in no way claiming that you cannot oppose Obama or his politics without being stupid. I'm merely pointing out that a large vocal portion of these people are idiots & refuse to actually use their brain for anything other than parroting some other more famous idiots.
