Islam Terrified of Atheism?!

This is a segment from the Oxford University Debate between Atheists and Muslims. Prominent debater Abdullah Andulusi ridicules the contention that islam or Muslims are terrified of Atheism/Atheists.



If you are strong in your imaan and believe in yourself, then I do not see why anyone would be afraid of anything except the most Forgiving.
''no one was intolerant to atheists in medieval islam''. ok i see ,,if thats the case why apostate should be killed as koran says. contradictions! aint it?
