I used to behave in a racist way
Seriously? Why did you behave in a racist way?
I am not sure to be honest. I just did it naturally.
Behaving in a racist way towards others is reprehensible behavior. You need to realize what you have done and the hurt that you have inflicted on others and apologize.
I do not get why people just do not get me. I am naturally racist and I can not change that.
I don't know what you mean by that. You need to apologize to anyone you have hurt with your past racism.
