Do you believe racism is an incurable ill, or in any way related to ones lived experiences and education? I have met (and still know) plenty of people that are varying degrees of racist, and the majority of it involves some pretty fundamental ignorance. In some cases people are outright indoctrinated into racism. I have no idea if this particular person was desrving of cancellation or forgiveness, but I can personally imagine someone at 17 writing racist sentiments, and genuinely repenting and growing out of that. I can imagine someone at 25, or 35 doing the same. I can appreciate it is hard to imagine that a person can change their world view, yet it certainly happens all the time.
