Inter-Racial Relationships

This is a highly debated topic, which I feel the need to bring up. Why is it that living in the 21st century people still have ignorant feelings towards two people that want to have a relationship just because they are not of the same race. Why is it that as a black woman people will look down upon me and my partner if he is of a different colour to me. Why is it that we have to work twice as hard as a couple that are of the same race, to say to the world that me and him belong together. Gosh things like this just get me so mad!!! Like there are still people amongst my own peer group that find the fact that a black person and a white person can be together is wrong. I dunno I'm one of those tolerant people where I believe that there shouldn't be an obstacle such as race stopping you from being with the one that you love.
