I struggle with this too. I’m reading White Fragility by Robin DiAngelo right now though and it’s main suggestion is to just oppose racism when you see it. Call white people out on their behavior even if it makes everyone uncomfortable and makes you unpopular.

Also, to listen to feedback from people of color without getting defensive. No one is going to be perfect and we live in a system which is constantly socializing us, it’s ok if we fuck up but just try and fix it when you learn better.
