Wrong. He is not blind to it. He is an enthusiastic proponent of it!
Obamas father was Muslim, and in Islamic law, he was Muslim by birth. He was educated as Muslim in Indonesia, the most populated Muslim country in the world. Obama knows their prayers, and praised them as the most beautiful sound in the world. He studied the holy Koran and Muhammad teachings.
Obama knows well the bloody history of Islam, but he still call it a religion of peace, even though that in the name of Allah more than220 millions infidels have been slaughtered by Muslim, since the prophet of Allah beheaded in 627 AD over 700 hundred men and the pubescent boys and enslaved the women and children. In doing this, he wiped entirely the last remaining major tribe of Jews in Medina: the Qurayza.
