Well it seems like anything will spark debate these days when anyone with a bias immediately "shares" something on FB without even reading the article. In this low-attention-span present that we currently have I don't think people even think about what it is that they are sharing before they do so but here is my perspective on this matter.
Buffalo Wild Wings is huge in America, and it is also one of my favorite places to go. I really enjoy a place that normally has like 20+ beers on tap and also a bunch of pub grub that while I know it is mostly pretty bad for you, is delicious and the prices are actually quite low. It used to be called "BW3's" and was just a small, regional establishment on the east coast and only had a few locations, mostly in college towns. One of the first ones was in the town that was my college town and man, was it popular. On a recent trip back to the states I noticed that BW3's is now almost everywhere, even small cities like the one I went to high school in and has a population of only 40,000 or so. It is a fantastic place if you love chicken wings and for me that is one of my favorite things. Whatever, this isn't a restaurant review.
For many people living outside the USA it would probably seem a bit crazy that someone would think it WOULD be ok to carry a gun into a restaurant - to be honest with you I think a lot of people inside the USA think it is a bit crazy. I'm one of those people that values freedom and feel as though you should be able to have guns and carry them wherever you want.... however, this does not preclude other rights.
I expect to be attacked from time-to-time when I say that I am pro-freedom and by extension of that I am pro-have-a-gun-if-you-want-to among a great many other things that can potentially harm others (or yourself). However, I am actually on Buffalo Wild Wings side on this one. It is their establishment, they own the building and therefore can (and should) be able to make any rules that they want to. If you, as a potential customer, don't like that, you have the freedom to take your patronage and money elsewhere or you can even be a dickhead and try to make some sort of campaign to cause them financial harm if you want to.
I would never do the last thing because I am lazy an find it easier to just not go there.
I can't help but roll my eyes when a relative or friend has a strong position of "good for you BW3's!" or "BW3"s is infringing on my 2nd ammendment rights!" There are even people calling for the government to force them to change this policy. It is their business and much like my house is my house, the owners of said place can have whatever rule they want (while this isn't exactly the case it is the way I, and many others, feel it should be.)
I am not sure what Buffalo Wild Wings is attempting to accomplish with this policy, especially since people who aren't overly concerned with laws (criminal-minded individuals) aren't going to arrive at this restaurant and then decide to not rob the place at gunpoint because of a window sticker. If I was the management of "Bee-dubs" (as we used to call it) I would have left this one alone because the unruly emotional masses are likely going to cause financial problems for ya!
