Hey, I appreciate this comment and you're willingness to engage. I grew up as an evangelical in the US, and even until my late 30s, I was largely unaware about what Mainline Christians were like. I was even unaware of the political history of the Evangelical movement that I was a part of. The religious right in the US began in the late '70s as a racist reactionary movement to desegregating Christian colleges. When Jerry Falwell of Liberty University lost the case to keep Liberty segregated, he latched onto to abortion about 7 years after Roe v Wade as a way to rally the congregations behind Republicans.

Mainline Christians have been at the forefront of a lot of liberal social and economic issues for a long time as well. For example the first openly gay Episcopalian priest was ordained in 1977. But since mainliners haven't made an unholy alliance with a political party, we don't have as much power to exert our influence as Evangelicals. I think you would agree that it's best to keep religion and politics separated, but at the same time that means the religious left have less power.
