I can't speak to privilege in other countries. Frankly, you can't speak to privilege in America, but you think ya can, and it's causing some problems for ya.
White privilege in this country doesn't mean that no white people ever suffered here. It doesn't mean no white people are suffering even now. It doesn't mean no white people ever lost everything. It doesn't mean no white people were ever falsely convicted of a crime. It doesn't mean no white people were ever executed for a crime they didn't commit. It doesn't mean no white people are in jail on drug charges. It doesn't mean no white people never really had a fair chance due to circumstances of birth, educational opportunities, bad luck, etc.
What it means is that, still today, realtors are caught redlining. It means that still today, studies show that people with names white people consider "black sounding" are much less likely to be called in on an interview for the same exact resume that has a white sounding name on it. It means that there exists severe sentencing disparities. It means that blacks are more likely to be brought up for the death penalty. It means they are more likely to be pulled over and searched for drugs. It means they are more likely to be followed around in department stores and treated as potential shoplifters.
All of these things, and more, have been proved in this country. And so, in this country, only white racists deny white privilege.
I don't know what it's like in your country.
