This is a pretty terrible misrepresentation of original sin. I see you managed to copy it straight out of the Wikipedia page and completely ignore the sentence before it:
> In Christian theology, original sin is the condition of sinfulness that all humans share, which they inherit from the the Fall of Adam and Eve.
> https://en.wikipedia.org/wiki/Original_sin
what does it mean a condition of sinfulness, the tendency?
like, if you ask a theosophist, which a I did the other day, he claimed it is not about sexuality or human nature at all. It is the sin of attempting to create a reality without God.
