This is another example of people believing that "second chance" really means "just reload the last save from your first chance and continue like nothing ever happened."
Which isn't how second chances work.
It's like - I get that people's misplaced empathy in these situations leads them to put themselves in the shoes of the repugnant idiot racist (or the sexual offender, or the drunk driver, or the sexual harasser, etc. etc.) and then entertain the scenario in terms of "Would my friends abandon me? I'd hope they wouldn't. I'd hope they'd stick around and let me know I was loved," and then proceeding from there like "C'mon guys, give em a chance!"
And that's understandable, yeah. But it's also selfish, and it's primarily seeking reassurance that despite your (hypothetical) idiocy people still like you, and that's not even the question here, nor is it fucking important to the topic at hand, either. It's turning a story about something seriously wrong into a what-if where you get reassured that people think you're okay down deep.
That ignores the concepts of personal responsibility and forgiveness.
And that's almost always behind this "second chance" bullshit when it's trotted out like this.
Racism isn't an opinion you give equal time to, nobody's fucking entitled to it, and your second chance in life doesn't mean you get to just start right back where you left off, you're just a little sorrier about it.
That's just the long way round to completely ducking responsibility and getting a fucking hug for it from your enablers.
Not your friends. Your enablers.
