Do we Amreicans form opinions based more on emotion, self-service, or logic?

I understand where you are coming from as I hear people make comments that are extremely general in content which always prove to be false. You can never say "all" of this or "all" of that do this....However, I know its easy to attempt to make an argument based on generalities vs specifics. I know many people don't like Glenn Beck on FOX. However, in almost every case I hear them attack him, and NOT what he states. Why? Because Beck shows videos of the person in question making his/her beliefs known, or reads their own quotes. So people take an emotional stand and attack him. We see this everywhere. In stead of ACTUALLY doing a little research, they throw out broad, generalistic comments. The same naive reactions occur in words spoken during speeches. People should know by now politicians tell people what they want to hear. Case in point, how many times have we heard Obama say one thing and shortly there after reverse stand. Latest was the Mosque speech and reversal the next day. It appears many take the easy way out, believe what they are told, and never stop to see the entire picture. This will be one of the primary reason we may LOSE the America we all know. Sure, it will still be AMERICA, but so much of what was originally given to us will be gone.
