If we had some flight instructors that had this same "racist" attitude, and refused to do business with enemies of the state there would be two tall buildings still standing with about 4,000 people in them.
1. Muslims make up 1.6 Billion, or 23% of the world. If you think we can not "deal" with them, then welcome to the 3rd world, of no oil, and no world influence, America.
2. The sins of the father are not upon the son. Or the cousin. Or the completely unrelated dude who happened to be born on the opposite side of the planet from you. To treat them as such is a sin of another kind.
3. 1.6 Billion. Right now not all of that 1.6 Billion are our mortal enemies, but given the natural instincts and resulting actions of some Americans, we might just pick a fight with nearly 1/4 of the entire planetary population. That's not exactly smart.
4. If you start down the road of selective reduction of options/rights/whatever of people, and do so by groupings of people, then pretty soon you are going to find yourself selected against -especialy if you are some kind of increasing minority (say gun owners, or caucasian, or rural who only make up 17% of the population and decreasing...). You open that door and on the other side is a bed of your own making.
5. PC is when someone says you cannot say something. Consequence is when you use your right of free speech, and I use either my right of free speech or association in response. It is not PC when people find a joke unfunny. They may just find it unfunny and not be interested in hearing the next. (not aimed at you, just a general point explaining the difference)
6. Muslims will eventually make up a larger portion of the US population and there is no changing that fact. People can either do their best to make friends with their new neighbors and help them Americanize/Secularize or they can wall them off, call them names, and later act surprised when it goes badly.
7. I find it interesting that so many who support a foreign policy that is arming Muslim nations to the teeth (Iraq, Afghanistan, Egypt, etc) with heavy gear, would turn and not give simple firearm instruction to fellow Americans due to religion. Seriously? No international terrorist is gonna take a CCL class from Jim-Bob. They have far better options than that.
8. We are in the midst of a soft war of minds and hearts with the 60% of non-gun homes of America and the 80% of Americans who live in Urban areas and are decreasingly raised with positive firearm instruction or connections. We lose the next generation of them and you can forget your grandkids' gun rights. The first way we win that war is by not shooting ourselves in the feet when we spout off our mouths and reinforce every stereotype of gun owners that exists. Self inflicted wounds are just the worst.
So, yeah, this guy might sound like a bucket of chuckles.
And those of us not laughing might sound like PC jerks ruining the locker room jokes.
But in the end he hurt more than he helped.
That's the point I was heading for...
