Triumph of the kudzu
When I was an atheist, I used to call Christianity a kudzu on Western civilization. A kudzu it might be, but an undefeated kudzu over the course of some one and a half thousand years is not something to be trifled with, and, like eyelashes and man, have to share a symbiotic relationship -it is no coincidence that the collapse in Christian belief around the world coincides with a collapse in global fertility (both to be caused by the negative postural effects of smartphones -they result in low back hyperflexion). I also used to call Christianity the biggest red flag there was -now I believe it is Christianity unassociated with the Roman Catholic, Eastern Orthodox, Oriental Orthodox, or northern national Protestant churches which is one of the biggest red flags.
