Iwonderhow much self-hatredis generated by shame, as a small child becomes moreself-conscious. Perhaps most people, even loving parents, haveinherited at least a little, thoroughly Freudian disgust with the body and its products, of which the baby is so charmingly unaware.
Then there is the emergence of less attractive emotions in addition to melingand crying, as the baby gets older: anger, tantrums, hate, yes, sexuality too, and much may depend on how such emtions are received in the first instance....
Saturn/Pluto are generally seenas the repository of all these 'basement' feelings, wherethe socialising child learns to Take Part in Society.
The Moon my indeed be about experience of nurturing, then again, the Sun can be about those first, shy steps towards dynamic self-expression.
I think, Michael, self-hatred is some thing that can be, should be, outgrown, and there is maybe no reason why you should not. Your Sun looks a little exposed in the First House - expressive house for a self-expressive principle, but in a somewhat shy, self-effacing Sign. And Virgo has been known to be self-critical. Perhaps you need to be constructively self-improving instead. And a Scorpio Moon square Mars - I have heard it said that Scorpio may feel that nobody on the planet has all the deep,dark, destructive emotions that it alone harbours in its bosom, but look around, and you may well find that that is not the case either. Perhaps your anger was not well-recieved in the first instance either, so maybe you need to find healthy outlets for your anger and capacity for self-assertion.
My two cents. Or pennies, or forint.
