There are many branches on the tree of US Christianity. [View all]
It's not just one religion with a commonly-held set of standards when it comes to social issues. Not by a long shot.
A majority of US Christians supported and voted for Donald J. Trump as President. In some Christian denominations, that majority was huge. Southern Baptists, the largest Protestant denomination, voted for him and support him by a large majority. Here on DU, we do not support him, even though many DUers are Christians.
Christianity isn't just one thing. Its followers represent a multitude of ideas, and Christians believe different things regarding both their religion and how people should be treated by the government and by the people, as well.
Some Christian denominations are strong supporters of human rights, but by no means all denominations. Both the Roman Catholic Church and the Southern Baptists, the two largest denominations of Christianity, reject the idea that women should have full control over their reproductive lives. In fact, both believe that using contraception goes against God's will, and abortion is a terrible sin. In other respects, too, women are treated as second class humans by both of those denominations.
The Southern Baptist denomination was formed specifically to support slavery in the southern states. That mindset still persists, and civil rights seekers have found enemies within that denomination.
Other denominations, although smaller, are more compatible with human rights and social justice movements. However, a majority of Christians in the United States still voted for Donald Trump, so there is that to consider.
I know many people who wear the label of Christianity. I'm selective of my friends, so most of them are solidly in the Democratic tradition, although I do have some family members who have racist and sexist tendencies. I have learned not to make any assumptions about people based on their declaration of being Christians, since over half of Christians in this country voted for Donald Trump, exposing their prejudices and ignorance.
So, I don't condemn Christians in general. Instead, I treat them as I treat everyone else. I wait to learn how they think, what they support, and what they believe on an individual basis. That seems the best way, I think.
