Sure it's convoluted, passive establishment, what a crock.
Let's examine the case of the gunsights.
It is legal to manufacturer gunsights with alphanumeric markings?
If yes, is it constitutional for the government to procure such items?
If yes, where is the establishment of religion based on that action?
Ah yes, you say the purchase of products with markings that can be interpreted to have religious meaning is ipso facto establishment of religion.
But you know what, that's a crock.
What the constitution say is that the government should neither establish a state religion nor should it interfere with the free expression thereof. The government should remain neutral.
So even though the gun sights have possible biblical references, they serve a secular purpose, which is all the Supreme Court, arbitrator of all things constitutional asks.
Which is why they have school lunch programs in parochial schools, and faith based organizations are funded for homeless shelters and Korans are provided to prisoners in Gitmo.
BTW even though i have lived most of my life in Georgia i don't qualify as a Georgia Cracker, but thanks for the compliment anyway.
Good to see you have such respect for the working man.
