There is not now and never ever has been a Christian or a non-Muslim named Hussein.
Hussein is an honored name in Islam as it is the name of a close relative of Muhammad. Many Islamic leaders have the name Hussein. Any Christian, as Obama 'claims' to be, or any other Infidel would be slaughtered by Muslims for using the name Hussein.
It has been glaringly obvious from day one that Obama is a Muslim, with a Muslim heritage, with a Muslim extended family. Those who refused to see or accept this did so because they willfully wanted to. The evidence of Obama's love of Islam and disdain for Christianity has always been overwhelming, right from the start.
