I absolutely hate, HATE, Parnavic (sp?) and Monty, and they are both European, I think. I found myself hating Mike Weir too because Canadiens would boast about how their lefty was better than ours (Mickelson). Sergio became likeable the older he got, he talked less and figured out his mental hiccups on the Tee that went from comical, to annoying, to sad.. Rory is irish, got to love anyone from Ireland..
So what's all this tell you? Actually I have no idea what that tells me.. I think it comes down to personality over national ancestry. Zach Johnson is a boring human being, or comes off as one on tv. tough to root for someone so vanilla. I like Bubba, he has some personality even if he berates his caddy. Give me someone with some charisma any day and i'll root for them
