Which would you say is the greater threat to Catholicism in the world today?

Islam or the Enlightenment?

The video is a debate on this issue between two friends at Thomas More College: Robert Spencer and Peter Kreeft.

Both movements are inspired by Satan, but isn't the Englightenmet current as it flows today a greater enemy? Which is a greater threat, a force which will eventually cut off your head, or a force that will corrupt your head and then your soul from inside?

I suspect that Satan's plan is to use Islam to give popular force to the Englightenment's proposition that religion ITSELF is what the world needs to eradicate, like a virus that will destroy everyone. Might it be under this movement that Catholics will down the line be rounded up and put against a wall?
