In any event, the business exemptions you cite were provided to various companies so that they could continue to provide coverage to their employees. If that coverage goes away, the individuals employed by those companies would still need to obtain coverage. And if this is not the case, then the exemptions provide yet further grounds for why Obamacare is unconstitutional because you don't get an exemption from the auto insurance requirement just because you work for a particular company that has ties to the Obama administration.
Well, I don't know about you but I have looked into obtaining certification for my Indian background to opt out of Obamacare. I'm not sure a Mennonite church would obtain the religious exclusion, but if so, perhaps I'd consider joining a congregation.
