How often does violence happens among people off different races?

Violence happens among different races way to often.

But it only happens if there is someone inciting the racism. Although some people react differently to it, some people can become very agressive toward another race because, that particular person does not like a certain race. But they are rascist because they believe that there should be one dominant race in this world. Not multple races ruling the world. But really we are all human, regardless of skin color. Color does not make one person smarter than the other and definetly does not give you the right to diss on a race that you do not like
