Bob saves! The end is near! Praise Bob! Insha'Boblah!
Oh, gods, I hope I don't actually start a cult dedicated to Bob... NO SHRINES TO BOB, YA HEAR?
This is America, wherein "Christianity" is a dominant cultural force. They can probably point to a dozen kids who self identify as "christian" who think getting married to your gay lover is a-ok too, doesn't really reflect on Christian doctrine.
It's true that freedom of religious practice isn't a blank check, but do you really want the .gov to have the ability to tell you what your religion says? Unless you're claiming Christianity requires you to cook meth in your trailer or something equally outside of any actual tradition then the .gov should shut the hell up. Unless the religious practice is a serious felony (and sometimes even then, see conscientious objectors and the draft) the .gov should shut the hell up and stay out of it.
Except how do you draw the line? Is there an age test when it comes to "respectable" religions? What about number of followers? Also, what do you allow as freedom of religion, and what do you not? Your claims that meth production is not a valid religious activity is near legally equal to dodging a draft. Both can be felonies. Meth production does not in itself endanger or harm the United States (consumption may, not production). Arguably dodging the draft does directly cause harm.
I don't disagree. I'm just saying, it's an extremely grey areas that lends itself too well to subjective limitations and not remotely objective ones. Legally, should Bob the Magically Pineapple (blessed be his pineapple rings, especially on glazed ham) be given the same respect as Vishnu or Yahweh? Why or why not?
