Do you believe society will ever truly overcome racism?
I do. However, I think the answer to making this happen is roughly my approach to encouraging it: simply not voicing the racist bullshit that you grew up with, and letting it die with you. I may occasionally think racist bullshit- but I'd really love for it to not live longer than me, which is why I try to avoid saying it.
Here's where the tone argument comes in, I'm quite sure.
It's only enough to let it die if everyone is on board with letting it die. Given that there are some folks actively trying to keep it alive, that means the rest of us need to put in some work to negate their efforts.
