You're full of shit. The law is unconstitutional by forcing people to do something against their religion. Govt is not he authority here. People are.
The law cannot even (shouldn't) consider religion. Just make the laws the society needs, while letting religious folks believe what they wish. BUT ALL ARE GOVERNED BY AND EQUALLY TREATED UNDER LAW ... or should be.
You're not getting it. Religion is not the intruder here. Govt is. The law passed by congress intrudes on a citizen's religious freedom and rights. The Constitution tells us the limits of govt, not the limits of the people. You're confused.
I agree with you. That is exactly what the Constitution does.
Instead of telling people what they can not do, it tells government what it can not do.
That is why I can never support government mandates to ban gay marriage.
That would be government telling people what they can not do.
