To the extent we want to find out how evangelicals formally deviate from Christ's teachings, we have to find a teaching he espouses, and then find a formal teaching of the evangelicals that contradicts that.
ND1IRISH probably knows that is a major challenge for several reasons (one being the lack of formal evangelical doctrine), but he is nonetheless comfortable making a sweeping accusation because it suits him politically.
It is possible that many evangelicals support Trump because of the border wall because they don't really want to engage in private charity as they are called to do. Is that hypocrisy? Or is it sin? Hypocrisy can be sin, but sin is not always hypocrisy.
It is also possible that many Catholics support abortion rights because they don't want to step up and live a Catholic life, and they don't want the burden of living with a child they created. Is that hypocrisy? Or is that sin?
In my experience, it is usually sin...that is, an inability to live up to a standard that one knows is valid in their heart of hearts, because it is too difficult for them. Or, it could be ignorance of their own value system. I think hypocrisy is actually very rare.
What if a majority of those evangelicals support missions to Mexico to help people there with health services and sanitation and food and religious training?...and host migrant families in their community? Are the evangelicals still xenophobic racists for supporting the rule of law in the United States? There is a lot at play here.
