This is a matter you'll need to work through on your own. You benefit from a system that is oppressive to people who don't look like you. Is your greater concern being perceived as racist, or the existence of systems that oppress those you consider friends? Consider taking time to ponder these questions privately. Approach discussions with individuals who have faced racism with a receptive attitude. Additionally, explore the concept of white fragility and its adverse effects on those who open up about their experiences with racism.
