Can Anyone ”Deconstruct” From His Christianity?

It is becoming a growing fad among many who seem to think they were once Christians, and now because they are enlightened, reasonable, or logical, they are no longer Christians. Christianity is a ”myth” to them. They are rational and no longer religious. But, have any one of them truly ”deconstructed,” much less ”deconverted” from Christianity? Or have they simply been fed a line of diabolic nonsense from some secular humanist philosophy professor, coupled with egregious discipleship at their former churches, and are now useful idiots (in the biblical sense) for the “Liberal” (a misnomer) agenda?
