The only reason my country has some cases of racism

I was born and raised in a country where 99.9% of the population among the 32 million inhabitants are black. And during all these years I noticed the racial difference between native blacks and native and foreign banks.
My country was colonized by the Portuguese, and many people had relations with Portuguese and generated mixed families, some white and some with a lighter skin tone. I have never witnessed or heard on the news or by people that someone was killed for being of another race, or someone discriminated against in a commercial, school, transit, or public square.
I am not denying that there are no racial problems in my country, but some racial situations that I have heard and witnessed are prejudiced. In my country it is still a big taboo for black people to be great friends with white people, you can see on beaches, there is always a group of blacks separated from whites, but that has only one reason.
The only reason my country has some cases of racism.
In my country, there is no social equality. Although 99.9% of the inhabitants are black, all whites live in it, none of them is a bank security guard, from an establishment, none white or white works as a supermarket clerk, there is no white taxi driver, there are no street vendors, that is, the lowest positions in the job market, are only for blacks.
The whites in my country are the big owners of the companies, the luxury offices, the luxury stores, the luxury cars, so they are hated by some part of the black population because they all arrive in the country in a short time, they manage not to bring their lives to the level of society, they are always the owners of everything that blacks need to survive, so then the reason.
For me, racism is a heinous act that kills the soul of the person who hates another person with a different color and poisons them.
Despite differences in social levels, we have no right to hate or take someone’s life for who they are. We must never hate a person. We may even hate acts, but hating the person is suicidal.
I am black and I have had relationships with white women
When I studied the third class, my girlfriend was the only white woman in the class, in the eighth grade the story was repeated, my girlfriend was also the only mulatto woman in the class. And look, they weren’t my first and only girlfriends, I’ve dated white and black women, and I’m finally married and happy in my marriage.
I never saw any reason to hate a human being, despite the discrimination I suffered from childhood to youth. But what I did was turn it around and overcome the barriers.
Today my best freelance friend is white, the brothers in the church who live with me are white, I made a segmentation of friends in my life to level what people discriminate, so they can understand that we are all equal and valuable human beings to society.
There are no whites and no blacks, we all have advantages and disadvantages, but we were all made equal and we deserve the same rights before each human being, despite the hierarchy that must be obeyed.
