Their reluctance stems, no doubt, from the fact that Obama denies that he is a Muslim. Of course, considering Obama's psychotic predilection for mendacity, his denial is the strongest evidence we have that he is indeed a Muslim.
But there is other evidence as well. His alleged father, Barack Obama Sr., was a Muslim. His step-father, Lolo Soetoro, was a Muslim. Barry Soetoro (aka Barack Obama) attended a Muslim madrasah in Indonesia. Barack Obama was born and raised a Muslim. And Muslims consider such a man to be irrevocably a Muslim – and if he does not embrace Islam, he is a murtadd (apostate).
The penalty for apostasy under Sharia is death. The fact that no Muslims are trying to kill Barack Obama is a petty good indication that he is a Muslim and that he is practicing taqiyya, the subterfuge sanctioned in the koran and by the ahadith of pretending to be an infidel to promote the cause of world-wide Islamic domination. Furthermore, the Muslim world is aware that Barack Obama is practicing taqiyya – because he has told them on numerous occasions.
In 2008, when campaigning for President, Obama told ABC's George Stepinawfulstuff that McCain had not attacked his "Muslim religion." Was that a Freudian slip, or was Obama deliberately broadcasting to the Muslim world that he is a Muslim?
In 2012, when campaigning for his second term, Obama told the press, "We've been in every State now but two. I think – fifty-seven states? One to go." The press glossed over this apparent gaffe as the result of pressure from the campaign, but Obama knew exactly what he was saying.
There is a "nation" that does have 57 states – the Organization of Islamic Cooperation (OIC). Every Muslim in the world knows that, and every Muslim in the world knew that Obama was using that known fact to advise them that he was practicing taqiyya. And in case they had any doubts, he threw in "one to go," a reference – understood by all Muslims – to Palestine.
If you didn't hear these and other messages advising the Muslim world of Obama's taqiyya, it's because you weren't supposed to. Taqiyya, after all, is a secret operation, and one has to apprise other Muslims surreptitiously. This is accomplished by using signals that only a Muslim would understand.
