Politically incorrect? They are shooting a .577 T-Rex, known to be one of, if not THE hardest recoiling rifle out there. Those vids have been all over the net for a long time. It is from a gun club in Dubai that specializes in big game rifles. There are PLENTY of vids of white people shooting the same guns there and having the exact same reaction.
The guy at the end is a German guy shooting a .700 Nitro and of all the vids they had on their site was about the only guy (Arab or Caucasian) to be able to handle it well. Probably due to the fact that he has had experience shooting those kinds of rifles. Notice the look of surprise on the faces of the ones falling/dropping the gun, they had no experience. It is basically like handing a 10 year old girl a 12 gauge loaded with 3" magnums and laughing when she falls on her ass.
