Is the point of this article supposed to be "Humans grow, so leave the vile stuff I said when I hadn't grown as much around for more and more people can see that I said it?"
IMHO the fact that the biggest font in this article is used to reprint the reprehensible statement is a clue that this author is actually resisting growth by implying what he said isn't actually that bad, and twitter should keep showing it to more strangers. Real growth would look like deleting the tweet yourself and looking for traces of it in your current language!
