The real problem isChristianityreligion. Christianity is simply the most powerful flavor locally.
Religion in the public square is nothing new. And atheists don't want to get rid of religion, they want to replace it with their own religion.
And what religion would that be?
The reason we have a cult of Trump is that many Christians are taught to believe in, and submit to an authoritarian figure (Jesus) as part of their religious indoctrination. They are taught to obey without question and act without rational justification. This mindset can be exploited by grifters and con-men (like Trump). They can be lied to, and often made to act against their own self interest, because their natural defenses to being conned (skepticism and rational inquiry) have been worn down through their indoctrination into the cult of Christ. They are ripe for the picking.
