Im sorry this happened to you. Racist incidents can stick with you and be impactful (negative or positive), and I really hope that it doesnt stick with you for long and impact your self worth. Just remember, and I’m sure you know this, you’re not below anyone. The aggressor/racist was a shit head and unstable. I’m glad you’re safe though because the fact that he followed is scary even if you’re with a friend at a crowded place. I hope he gets caught some day if not soon.
