My paternal grandfather was killed in WW2 in Europe. My paternal grandmother served in the WAC. They were both “undocumented immigrants” from Poland.

My maternal grandfather was a Marine Corp Reservist, but was not called up because he had a critical job as an engineer at Ford. My maternal grandmother and her first cousin both served in the WAC.

My father was killed in the Vietnam War in the Navy; my mother served in the Navy during the Vietnam Era.

I’m not terribly interested in being wished a “Happy Memorial Day.”

That said, it would be difficult to change a nation’s attitude about this. That said, it’s kind of the point of liberty. The government isn’t telling you what to do with your time (and business needs to make money on what was a solemn occasion).
