Why are Asians racist to blacks?

they'll sell our food,take our money,open black hair and beauty shops but remain ignorant towards us, like not putting the money in my hand and talking in their lanuage whenever i enter their shop,etc, why is that? i remember back in the day when asians and blacks use to stick together. when they use to get their windows smashed,beaten up etc from the National front gang it was blacks that were saving an defending their azz. Now they've made it big, driving around in their big fancy cars, opening banks, shops,buying up houses etc they don't want nothing to do with us, they look down on us like we're nothing, but yet at the same time they will open shops catering for black people,why? why not give blacks a chance to do their thing.? why are they taking our business , how would they feel if a black person opened a indian resturant? i could go on and on. i am not racist to asians but feel angry at how they treat us.
