You are correct that Bruskewitz is not the one that should be sent this letter. But this letter should be sent to the majority of Bishops who are, in general, a bunch of socialists. As Rush says, liberals are liberals first before they are anything else. E.g., Catholics, Feminists, Jews, Environmentalists. I have heard several devout Catholics state that the Bishops brought this on themselves.
The trouble is, they didn't bring it on just themselves. They brought it on all of us. Even if Obama caves and exempts Catholic hospitals, universities, and similar organizations, what about the Catholic owner of a business? He will be required to include contraception and abortion in his company's health plan. Either that, or pay a fine for not having a health plan. This affects many more people than just the Bishops, and church employees.
