I know nothing he said suggested the slippery slope, you did...and still are.
MY point is that in cases in which you have non-religious reasons to keep a law, that's what you use. Any religious reasons are moot. We can GET RID of them.
There is no non-religious reason for businesses to be closed on Sundays. There's no reason for any business to be closed on any particular day of the week. They are private entities and are free to be open or closed on any day(s) they wish.
Each state needs to have a spring cleaning of it's antiquated, bullshit laws that never got around to being dissolved.
No, let's let the establishment clause get in the way of common sense.
I'm not well-educated in law, of course, nor do I wish to be. I have enough bullshit in my world already.
