Yes, he is entiled to say what he believes, and so are you. However, someone has to be right about the subject. As to the Asians, one of the notable thing about China is the growth of Christianity among the Han. It would be nothing new for God that as Europe abandons the faith that defines it, that China might accept Christ. But the two contestants for the souls of man are Christians and Muslims. Islam is certainly making more noise right now.
Actually, I didn't say he is entitled to say anything about Christians. Frankly, I think people should shut up about other people's religious beliefs. It's obnoxious.
