I have seen more "refuse" in Christians then in any other faith because they pretend to be "like Christ," possessed of the Holy Spirit and what not, and being like Ann Coulter. I, certainly, do not exclude myself in that group. We all do things we preach others shouldn't!
Those who are not Chirstians are just who they are. They have no reason to be Christ-like. Christians have no excuse. But, I have not recognized Christ in 99.99% of Christians, and the 0.001% that may be, I have not met.
