Wow dontbelieveinmyths, you are totally clueless and insensitive. As an Asian person growing up in the Mainland the "slanted eye gesture" and racial slur (similar to "Chinaman") was used to taunt and harass people of Asian ancestry and is considered extremely offensive. For me, it was cause for a fight and I would not take that type of taunting from anyone. It's equivalent to using the "N-word" and your saying we need to thicken our skins?  Yeah, right, you need some training dude!
