Imo, racism would most likely still exist. You're forcing them to succumb to terms that they don't want to agree to, through the use of violence. Of course, provoking someone without a plan would be unwise and irrational.
No one wants to live near people who are so easily provoked. Which is why national borders have become more of a problem and not a solution to anything. Its as Nikola Tesla said "It is by abolishing all the barriers which seperate nations and countries that civilization is best furthered." Nationalism is a form of hatred which almost always lead to some form of unecessary conflict. Whether this conflict is a foreign or domestic one.
I'm going to be frank about this, and keep I'm mind, that I don't mean what I'm about to say in a disrespectful manner: I find you rather ignorant, in general.
Now, let me ask you a question: what do you think the world would be like if national borders and religion didn't exist?
