Racism is the prejudice and discrimination of other race with the believe that one race is superior to other race because of particular prejudiced features. Racism is the bedrock of the problems we are facing in the world right now and no matter the fight against racism, more racists seems to crop up daily.

You become a racist when you hate or dislike people of other race that are different from your race for no good reason. Not that they hurt you or anything but because they are just different, you become prejudiced against them.

The moment you see yourself hating on others from another tribe or race different from yours and generalising your hatred to every member of the other tribe or race, you've eventually become a racist without you knowing.

Irrespective of our physical and historical differences, we are meant to be at peace with every race and treat ourselves equally as humans because we are first regarded as humans before being regarded as members of our race. Unfortunately this doesn't happen. The whites regards the blacks as filth, the Chinese and Indians regards themselves as brown and yellow etc. But we lose sight of the fact that we are all humans.

Secondly, the family orientation and societal norms you were brought up with also goes a long way in shaping you to become a racist. If you are born in a society where other tribes and race are regarded as inferior as the case of england and America during the trans Saharan slave trade, you'd eventually be socialized into the mentality that you and your race are superior to other races. This might not entirely be your fault but that of the society and the socialization process you passed through.

My advice for you is that, the moment you see yourself haying on other races think of them not as members of a particular race but as humans.
