@wonderingwhy I agree it is a nice idea to have holidays that the whole country celebrates that are void of religious connection. I consider Thanksgiving and July 4th to be that type of holiday (although, I had a long Q with people arguing Thanksgiving is religious). Both of those I prefer retail be closed for the most part, and also New Years day. It really annoys me the malls started opening on New Years day. The rest of the holidays, even the religious ones, I think it should cater to the community, and have understanding for the employees. Some stores are now open Easter Sunday where I live, which I think is ridiculous, but where I used to live I think it would have been fine, because so many Jewish people lived there.
We of course have other holidays like Veterans Day, Memorial Day etc, which also are secular and some communities I have lived in do more on those days than others.
