Do you find that you click on the threads anyway because you hope, even though there's a chance of remembering and you acknowledge that, to not remember the things and try to act as though you've gotten over it? That would probably be the case with me, though I don't mean to imply that I can empathize myself so much as to put myself in your position, as I am 100% sure I have no idea what it's like to go through what you've been through.
But one thing I guess you could try to do is create new perspectives to what you think of something when you see it, and try and make your first thought of what you see/hear something else than it is now. I'm not really sure on how to do that, but it's just one of these crazy mentality tricks I myself have. If I were to do this, I'd create new memories with those words by hanging out with friends more and talking about the views of racism and other stuff, but I don't think this is a very good way of going about this problem, but personally, it'd be the first thing I'd do.
Sorry that I misunderstood you the first time. Thank you, you two for making me understand better. Let me apologize for my misperception (word?).
I agree with helms now. Another reason I had thought of was that you have some hope that there is a problem in that thread similar to yours and you want to help that person because you know what it's like, even though you get reminded of incidents in the end. Helms has put anything I would want to say in a better, more relative tone than I would, being as though he knows you better than I do.
I don't really think my post poses much validity (word?) now. Sorry to post something that doesn't help much at all :T.
