I need advice...even bad advice...?

I've had a friend since high school. We're both 45. She's a neo-conservative religious right type person and I'm an atheist. I'm working on my degree and minoring in human rights. She believes blacks are lazy and the white man is getting the shaft because he has to work harder to carry the black man. She abhors homosexuality. I'm a live-and-let-live kinda girl. I love her, bottom line. I do, however, believe she is being willfully ignorant of facts and statistics about racial divide in economy between blacks and whites. I can cite studies and have. She says she can, too, but is "too busy." My reasoning says to get out of this relationship while my history with her says I should just take her vitriol as her opinion and not engage her. What would you do?
