I just see no evidence that says they hate us for our freedoms. To me, this all seems just like a bunch of speculation, without any solid proof. Have the terrorists ever said "we hate you because they missed the boat." The author didnt actually give any proof, just a series of logical thoughts that ended up with a conclusion. I could do the same.

I mean, maybe they hate us for our moral corruption. Maybe they hate us for 50 cent, britney spears, pornography, fear factor, girls walking around whilst showing their panties, and blah blah blah.

Just mear speculation.
