なぜ韓国人は、嫌われるのか？

It's said Ahn's customary made such stupid abusive comments;
(quoted from somewhere)
> Korean men are better with women.
> Whilst in Perugia, not once could he find a decent Pizza.
> After a close comparison, he prefers driving his Hyundai to his Ferrari
> The number of quality Italian sportsmen is matched only by its number of War Heroes.
> The Roman Empire would never have been built if Korea were closer by
> Da Vinci would have been considered an 'average housepainter' in his day by Korean standards
> The Ninja Turtles had given more to world culture than their Italian namesakes
> Italian fashion still had a lot to learn from Korea
> The red card wouldn't have mattered; Korea can, did, and will continue to kick Italy's ass anytime, anywhere, so get over it!
and something like that.

You can tell he is really typical of Koreans who always say bad things about other peoples.
Especially, it's so sad that he said something that insults Perugia and Italian soccer.
He was returnig evil for good.
I don't understand his arrogant attitude.
