If you have ever filled out a VA 40-1330 (Application for a Standard Government Headstone or Marker) you would have noted the high number of religious choices.
Haven't filled one out, but that is a good practice. I know some would not be on the list, perhaps do to low volume of selection, but would we allow the family to supply a headstone/marker with the symbol of their choice?
We can eliminate the Swastika because it is a political symbol rather than a religious one, but there might be others not on the list offered.....again, a satanic symbol comes to mind as an extreme example.
Also, if the Marines in the example that started this thread had chooses a satanic symbol (and I know that is very far from likely) would we allow them to put it up?
I ask these questions even though they are way at the extreme of possibility because that is the way I determine if my logic/reasoning is right. If it does not work for me at the extremes of the situation, I need to think about it some more.
As for "the wishes of the majority"...
Our country may soon have a majority of Hispanic or Muslim population.
If there is a Hispanic majority, should the national language be changed to Spanish?
And should the majority becme Muslim...and I mean peaceful Muslim, should they be able to take back their religion, should the Pledge of Allegiance read "...one nation, under Allah.."? or Satan, again using that unlikely extreme as a test.
