Ray Arcel, his trainer, felt that Duran needed to visit a psychiatrist after that loss.
I tend to think that it was the case of a massively over-blown ego and the process of being humbled. Duran was at the top of the world and was starting to take things for granted. He only had one loss, which he avenged twice.
I don't think a blanket statement about a demographic should be deemed racist automatically, because we're all pretty much guilty of having made such statements. Sometimes it's just to stir it up and start an argument. Other times it's just intellectual laziness.
I'm not going to pretend to be much better in this regard, a lot of times I throw out a weak-ass, stereotypical statement which is provocative, in order to get a discussion going. People are much less likely to debate a statement that's rock-solid and difficult to challenge from any angle. But I didn't necessarily come here to be agreeable. I come here to get some debates going, and a bait statement like "Muslims/trannies bad", is a good way to get it going.
I think the threshold should be as high as possible for warnings and bans.
