Forwards, I'm an act of art With lines and shading I appeal Backwards, I'm a safeguard An occult or mystic shield

As a whole word I'm a grungy little spot, a place on your body either feared or sought. Take away my first letter for a Southern clue, that someone's not about to do the thing you'd like them to.

I appear as a choice, but I am not dependent on only one. People associate me with democracy .

By some definitions, I’m counted alive, since I eat and breathe, multiply and thrive. I’m bright and warm, with a merry sound, yet was never born, the mysteries abound!

Take away my first letter, then you suddenly have options aplenty. Put it back, then you gain the ability for a progeny. What am I?
