are typical of several denominations, e.g. Lutherans, Presbyterians, Episcopalians, and several Methodist and Baptist churches, as well as some smaller, lesser known denominations, and many predominantly African American churches. That's an awful lot of churches all across the country. Millions of people.
I grew up among Catholics and have seen the things that you mention. But they still operate Catholic charities, hospitals, universities, and immigration services. They are losing money and members due to the sex scandal and their political positions. There are former Catholics in my church who left over being told to vote for anti choice candidates. My church's position on abortion is that it is a serious decision between a woman, her doctor, and her conscience.
There is a divide in Christian churches on social issues as in the rest of society. The evangelical fundies are the loudest, most political, and get the most attention. But in most mainstream churches there are no hellfire and damnation sermons about or exclusions of LGBT people, abortion, feminism, welfare queens, etc. They emphasize Christian principles of love and acceptance. They oppose the merging of religion and government. They challenge people to examine prejudices and eliminate them.
I am not selling religion to people who don't want it. I am just tired of sweeping generalizations that lump everyone together without knowing what is really happening in many churches. Most often the generalizations come from people whose negative experiences turned them off. I don't discount their experiences. But I disagree with sweeping generalizations based on them.
I respect people who simply can't accept, on a rational basis, the theology and tenets of a religion. I've had enough history, anthropology, and comparative religion courses to not take religion on a literal basis, and to understand both the positive and negative roles of religion in a society. For me, religion offers a framework for values expressed in traditions and stories whether or not the stories are literally or historically true. I look at the context of time and place to know where they are coming from and what they are saying.
I don't reject all of religion because of some of its history any more than I would reject the Democratic party because of Southern Democrats during Reconstruction, or because of some members like Senator Robert Byrd. I look at what the party is and does today.
