You're right...I guess they really do hate us for our freedom... All along I thought it was because of our interference in their liberties. Thanks for setting me straight.
Strictly speaking, it's not "for our freedom" except incidentally. It's because we are not Islamic and do not acknowledge the supremacy of Islam.
The Western World went through the Enlightenment, where ideas such as the dignity of the Individual, the separation of Church and State, and Freedom of Conscience (of which Freedom of Religion is a subset) got their footing. Most of the Islamic world has unfortunately missed that.
