If you don't believe people can change their views and expand their mind than this forum should not exist. Most everyone here held different views and through one individual did many people learn truth, but through the individual.
I am not one of those people, but to deny this fact only shows you blindness and pseudo-anger towards an individual who objectively is doing good. It reminds me of Our Lord when He said that if someone is casting out demons on the behalf of the Devil how long can evil last even under those premises. In other words, if a "neo-con like Beck" is doing good on behalf of goodness, even with a nefarious and evil belief he is "hiding", how long can that nefarious and evil edifice last?
If you actually "think" about it, you'll realize you are the problem. Imagine if Ron Paul took your position when explaining himself. He would have wrapped things up in his 30's or 40's and said, "Well they just won't listen." Patience and trying to believe in good-will over your subjective beliefs on someone should be the key.
