Please stop with the 9/11 jokes. My dad died 16 years ago today. I still remember the phone call he had with us on the plane, and I remember his last words. "Allahu akbar!"
I'm not very comfortable with the point you're trying to get across here.
It had a huge impact on my life. I am still pretty sad.
Sympathizing with terrorists is synonymous with supporting acts of terrorism. You should mourn the loss of the innocent victims without supporting such radicalized tactics.
