How do you compel a retailer to sell guns to 18-year olds while allowing a baker to sell wedding cakes to straight couples only? I read on forums from many commenters. including a few members of the intellectual class. The right-wing answer is as follows: "Gays, rental cars and hotels are not mentioned in the Constitution. But guns are specifically mentioned in the Bill of Rights".
In all practical matters, the decision of Dick's Sporting Goods to restrict gun sales to 21+ is a boon to local sportsman stores. (Walmart has come to the same conclusion, but read below for my verdict). These local stores presumably have regular contact with county law enforcement and support public safety while serving customers. This face-to-face contact is something large corporations cannot achieve, with directives from coming from headquarters from a state far away. .
One might mention that hotels and car renters restrict to 21+. Often, a hotel will waive age stipulations if a company, especially the US Military, will foot the bill. Understandably, a hotel is at stake if young Spring Break revelers trash the room. For car renters, an age of 21 can serve as a proxy for "five years of licensed driving experience". Indeed, inexperienced drivers are more likely to accumulate a claims bill! Requiring auto rentals at 18 would create an undue burden on car rental companies. I went to college in New York and benefitted from the state's requirement of renting cars to 18 year-olds. (I'm a good driver, as everyone thinks they are). Now turn to guns: Due to the legal precedent in this nation, gun sellers do not face liability if their customers raise Cain with the products they sell.
I believe that discriminating against customers is sheer stupidity. I feel that African-American economic empowerment in WWII was a significant factor in securing equal rights under law. Integration of the military was very important as it gave African-Americans buying power that they didn't have before. There was the "Don't buy where you can't work" movement in the 1940's, referred to in August Wilson's Fences. After WWII, Woolworth's and other interstate chains no longer had incentive to racially discriminate asides from local regressive laws. Indeed, I read that southern Woolworth's were encouraged to 'discriminate politely' so as to not offend the northern African-American market. BS.
In Virginia where I have bought a condo, since the same year interracial marriages were allowed, alcohol licenses have been issued to restaurants, while taverns have been outlawed for 100 years. Notably, restaurants and hotels are subject to more stringent anti-discrimination laws than other forms of privately-owned venues. Concealed-carry weapon owners have been able to carry in "bars", and the ability to create a 21+ environment is limited. Most often, age restrictions in alcohol-serving establishments will not apply until 9 or 10pm due to the fact that an establishment must function as a restaurant to qualify for a license. This is in a "commonwealth" which does not treat homosexuals as a protected class.
I suspect that Walmart's board of directors anticipates a letter from an "Attorney General of xx southern/western state". With that, they will "suspend efforts" to restrict gun purchases to 21+ in compliance with the law. As a further aside, posters on gun forums have commented that they didn't even know that Dick's sold guns. If so, they were overpriced. They should focus on selling "concussion causing" footballs to gym teachers.
