Assalamu alaikum bro. First you have to realize there is no Racism in Islam. But you will find many Muslims who do not follow Islam properly and behave in such bad manner. Just like you will find some muslims who drink alcohol, but it doesn't change the fact that alcohol remains forbidden in Islam. Be patient bro, Allahuma'assabireen . Allah is with the one who is patient. May Allah make it easy for you, ameen.
