Since sincerely held beliefs get you out of following important laws like equal accomodations for public businesses, they should get you out of less important laws as well.
So, let me state that I believe I should be able to drink Two Hearted Ale anywhere, anytime. And I guarantee I believe this more than many Christians believe their faith. And I practice my belief more than many so-called faithful practice theirs. You might say these beliefs need to be 2000 years old (or maybe 150 if you want to include Mormons), but how long has beer been brewed? 5000 years? Beer drinkers deserve their accomodations more than all these young monothiest cults. Even Judaism is what only 3000 years old?
Also, in case that guy hired to work Sundays wins his USPS case that he doesn't have to work Sundays, the cult of the Two Hearted has its Sabbath on Wednesdays.
