What are Southern attitudes on inter-racial marriage and gay couples today?

I remember reading some pages from my history book today that if a black man were to ever lay hands on a white woman, no matter what reason he would be good as dead. A black man who had with a white woman was considered a mad-crazed maniac and a rapist. When a story got around that a black man was accused of raping a white woman, the rumor would circulate really fast and people would demand for a speedy trial. Every black man knew at that time that there was no justice. Newspaper editors took the side of the lynchers. They cautioned readers not to take the vigilante road but they remained partial towards people who did murder black men for sport. Southerners were always energized to form lynching mobs, demanding that justice be exacted through vigilante violence. For example when news got out that 9 black men d two white women in the 30s the whole of Alabama was seething to lynch them. The black men were wrongly accussed of a crime that they did not commit but the Southern courts tried them anyway and they eventually did rule the death sentence. The point is, in the eyes of the Southern legal system a black man if proven by testimony d a white woman deserved to be legally lynched. Why is that? And how has that attitude changed in the South? What about gay people living in the South, do they feel the same kind of intolerance directed at them as the black minority experienced back then?
