I'm not cherry picking though. Evangelical christianity is mainstream. Those churches I mentioned? One of the pastors was asked to pray with George W. Bush after his inauguration. 

Most major political candidates give speeches at Liberty University (Trump read from "Two Corinthians" during one of his speeches). 

Mike Pence is extremely open about his agenda and his faith. Then you have the likes of Sara Palin who you can openly find videos of her praying and preaching about this being a Christian nation. If anyone was remotely that devout or dogmatic about any other belief system you can imagine the reaction.

Evangelical Christians are the most influential religion when it comes to American politics and they also pretend they are the most persecuted for absurd things like gays being allowed to marry or not being allowed to put a cross up in a public square.

Meanwhile you have articles like this where Muslims feel they have to change their locks because their lives are threatened.
