Why do blue laws still exist?

Blue laws are defined as Unites States laws that were originally designed specifically to enforce religious standards. While many have been deemed unconstitutional and have thus been overturned, most states still have laws banning the sale of alcoholic beverages and restricting commerce on Sundays. The rationale behind the Sunday restrictions is that people should be in church or respecting Sabbath instead of drinking or shopping.

Blue laws seem to be more extreme the father south you travel. While my husband and I were driving to Florida last year, we decided to stop at a Ruby Tuesday's late one Sunday evening for dinner. I attempted to order a glass of wine to go with dinner (it was our anniversary), but the waiter just stared at me in shock. "You do realize it is Sunday, don't you?" he asked, with mouth agape. I quickly realized my mistake and apologized, but he continued to examine me with a concerned glance which clearly read "I think you are a sinful alcoholic."

The most extreme examples of blue laws are dry counties, which can be found all throughout the southern states, including my home state of Tennessee. Dry counties engage in varying degrees of prohibition; many do not allow the consumption, transportation, or sale of alcohol under any circumstances. Critics of dry county laws suggest that prohibition actually leads to higher incidences of alcohol related crashes considering residents are forced to drive father away to drink. Additionally, many studies have proven that moderate alcohol consumption offers many health benefits, including decreased risk of Atherosclerosis.

If separation of Church and State is a guaranteed standard of American living, why do blue code laws still exist? Many U.S. residents are still forced to live under regulations that are centuries old, and repeated attempts to overturn them have failed. How is this not considered religious discrimination, considering the fact that the "Sunday laws" apply only to Christian principles and do not offer Jews and Muslims a day of worship? If the U.S. chooses to legislate morality, how to we chose which mediums of morality to enforce?
