@Porpoises I'm glad you asked about the emotional side. As a white person, I can't really discuss this on the usual threads because it isn't appropriate.
I think it's incredibly important to approach anti racism from an educational perspective amongst white people, otherwise you risk alienating people and it could actually damage race relations. I think language is incredibly important.
I'm going to use the example of a white person who inadvertently makes a racist comment, either in person or on a social media platform. It is absolutely appropriate to call them out on the comment, tell them that it is offensive (and why) and point out that they could have deeply hurt someone. A large number of white people will be horrified, will apologise and learn from the experience. If you label that person (rather than their comment) as a racist, that's where the trouble starts. You are lumping them into the same category as people who commit hate crimes and that's when people get defensive. If you treat white people who make a mistakes like monsters (as happens a lot on social media) then resentment will build and race relations will be damaged further.
