I think this effect is actually highly dependent on who you are. In my experience people have actually become more open to discuss many subjects with me. I'm also visibly nonwhite in a white-majority country. In my youth, I was frequently bullied, harassed, and made to feel unsafe because of my nonwhite status. This has become less acceptable now that I'm older. I've also found I feel safer in cutting out racists from my social circle, whereas in the past I had to smile and accept being told immigrants like me are shitstains on the country while I am "one of the good ones".
