Johnny-come-lately “revelations,” such as Islam and Mormonism, always feel historically inferior and attempt to build a faux history for themselves by reaching back into the past and proclaiming that such and such a figure was REALLY a [Muslim] [Mormon] [fill in the blank] all along.
I’m also very amused to see occasional proclamations by various Muslim nuts, such as Ahmadinejad, that the Muslims really “invented” this that or the other thing, while they clearly did not and barely even know how to use said invention (well, except for the lethal ones - they’re pretty good on mastering stolen weapons technology). It reminds me of the bad old days of the Soviets, who were always announcing that they had “invented” things like electricity, running water, etc.
I was kidding about the Mormon thing.
