On the one hand it does lend credence to their claim to actually be young, because anyone old enough to remember it would recognize that as radioactive reddit-tier cringe. And going through a "they just haven't heard it yet" phase is practically a rite of passage of secular anti-authoritarianism.

But on the other hand, it's incredibly counter productive. Because the believers have in fact heard it before, and any form of serious right coalition that hopes to have the numbers to do anything practical will have to involve an alliance of traditional believers and a-religious people who nonetheless still strongly believe in Christian adjacent moral values and traditions. You can't fracture along those lines without losing disgustingly, for either side. For the traditional Christians that's an easier pill to swallow nowadays, since half the organized churches are soddomy promoting, abortion loving heretics. So even an atheist can seem more like a brother to the actual moral teachings of the bible in comparison, even if they're reaching the conclusion by different means. The firebrand, secular anti-authoritarians just need to look around at all the forces arrayed against them and ask themselves if they really should be sparing any energy to argue with people with the same practical end goals but might occasionally just ask if you want to be saved spiritually. Instead of devoting all your energy to fighting the people who actually just want you dead and your children despoiled and mutilated.
