People who believe in family, religion, their view of America, etc., are allowed their beliefs just as you are allowed yours. What neither group, them or you, are allowed, is to impose one set of beliefs on the others.
Keeping Church and State separate, does not kick Church out of the Public Square. It does not prevent them from seeking exemptions from certain rules that cover how they teach, or how they preach. There is a controversy at the moment, a valid one, about religious adoption centers and GLBT children. A number of states have no adoption centers of their own, they rely on religious and secular ones. Some of the religious ones, refuse to give a child, who says they are gay, to gay parents, or any child to gay parents. This is wrong. If they cannot do so, in good faith, they owe the state, which helps fund their mission, to give that child to an agency which will do so. Forcing them to do so, will only lead to a decline in the number of agencies, and over burden further those secular ones that are seeking to do good.
People of good faith can find common ground, to support both the state’s and the religion’s articles of belief. This is only one area, there are many more, and with a little bending on both sides, much good can be achieved.
To many people, on both sides, are for all or nothing. That is an impasse and will only lead to further strife. Your reply was filled with the very same sense of deserving to be above it all, that people on both sides all to often exhibit, it does neither much good.
