Is this illegal discrimination? No, of course not. Are any of the "yes" votes going to defend their position or should we just assume it's all knee jerk hatred of anything religious?
Considering I'm a Christian who "yes" voted, no, don't assume it's a knee jerk hatred of anything religious.
The intention of this promotion is clear - if you came from church, you don't have to pay as much - it is favoritism to the religious. Sure, anyone can go grab a bulletin - but then what would be their motive behind the promotion, are they bulletin hoarders?
No, of course not. They're purposely giving people a discount for being good church-goers, and yes there's the loophole of anyone can go grab one, but there's nothing they can do about that and they realize 99% of people with a bulletin probably actually went to church. This is an intended form of discrimination against the a-religious, and to me doesn't hold up for that reason.
