then why do they still close on sundays?I gonna say this - the local owners don't usually have the same conservative bent as the previous CEO. Also, they've moved away from that focus that they previously had. This is a pretty good story on how they have changed:

Edit: people seem to be missing this - the old CEO stepped down and a younger one took his place, modernizing a lot of their organization with a direct edict to engage all beliefs and people. Yes, the organization still had it's conservative roots, but they are trying from the top down. Disclaimer: I was one of those who boycotted originally until the CEO changed and they stopped supporting anti-gay organizations ... And they did that.
