If enforcing instance-wide rules is an issue for you, I have bad news about any forums you choose to join in the future.
Not only is it against instance rules, but the comment was reported multiple times for being hateful and offensive, if it doesn't personally offend you that is wonderful, it doesn't change the bigoted nature of the word, and that it does offend some people. I gave OP 3 hours to edit the comment before I removed it, if anything that's quite the opposite of Reddit moderation, where you'd simply have a comment removed and receive a ban instantly.
He's been banned and (most) of the comments removed.
