As far as the video I find it interesting I cannot find a website for this socalled group. I find it interesting that groups credited with inspiring this video says its target audience is the and I quote the "uninformed."
What is relevent is how Muslims act. And there is a problem with the extremists and the problem is getting worse. The real question is how do we best deal with that IMO. Muslims have been so busy fighting each other through history the real danger will come if they have a common enemy and we did exactly what Bin Laden wanted. Muslims in general want jobs and a better life for their kids. Revolutions and wars will come out of desperation and poverty. That is the real problem. The extremists have fertile ground now.
The whole theory of abrogation is interpreted differently by different Muslims and it is a problem with the extremists and not the majority. How you and I interpret abrogation is of no consequence.
