The Rev. Gene Youngblood says the sign at the entrance of First Conservative Baptist Church and the Conservative Theological Seminary may be controversial but it has been researched and speaks the truth. References to specific verses from the Koran and the Bible accompany the statement, which Youngblood said are meant to serve as a warning to society. "I am of the opinion, based on enormous research of the Muslims' own books, that Islam is the most vile, wicked, evil danger facing the world today," Youngblood told the Jacksonville Times-Union. He said the sign was inspired by this month's London terrorist bombings. The church displayed a sign in 2003 declaring "Muhammad approved murder." Youngblood runs a Web site — www.truthsthatfree.com — that portrays what he considers to be the truth about Islam. Muslims condemned the messages as hateful and ignorant.
