I am not sure where you guys are getting this impression of Harada from. Is it an interview he gave somewhere? Was it something he said on Twitter? Was it some panel you attended at GDC or something?
I am one of the few people who have met both Katsuhiro Harada and the guy who calls himself "Razor" Ramon (and I'm not talking about Scott Hall) and I can honestly say that Harada was cool/gracious/funny and "Razor" was a loud, obnoxious asshole and one of the first things out of his mouth was "I hope Nick dies from germs". But hey, some people find that kind of shit cool, so who am I to judge.
