The conflict goes back much further than that. This is just the latest chapter.
In this chapter, the split may go deeper, and divide Evangelicals against themselves, rather than against mainstream or liberal denominations, but it may be shallower, more about Trump's behavior and style than about religion or politics.
One could make the counter-argument that everything is about religion and everything is about politics, but in this case there are a lot of people in between, people who support Trump on the issues but don't approve of his behavior or style.
A large problem is that the media has created liberal and conservative wings of “Christianity”, despite the fact that there is nothing remotely Christian/”biblical” in gay or female ministers, support for “gay marriage” or abortion, etc.. These “Christians” aren’t even attempting to link their social engineering/environmentalist BS with Jesus Christ; He isn’t the focus of anything they do - yet the media maintains the fiction that they are “liberal Christians”.
