Why do people think white girls are the most ually promiscuous?

Wow. 1) This is a completely ignorant question. 2) Turning a nonexistent stereotype and slamming "black women" is beyond racist. To be honest, I've never heard an "angry black woman" spout as much ignorance as you've so kindly displayed here. Your entire theory is such a huge generalization, I couldn't take anything you've said seriously. 3) The prevalence of STD's and children out of wedlock have nothing to do with promiscuity.
