it's OK to speak out against the wrong's of Trump, but don't ignore the wrong's of the left. The Democrats are the party of many things hostile to Christianity, including atheism, abortion, drug use, and more.
It could be an easy decision for any Christian to be a Republican, except for the fact that the Republican agenda is against economic equality that Christ would surely espouse. The draining of resources away from the pure, the proposed tax plan that benefits the wealthy, and more. Simply put, there is no political party for the true Christian.
McClelland is my former pastor, and I know him well. He is well-meaning, but I don't believe he recognizes any of the problems from the left side of the political spectrum. He totally minimizes them.
