I'm not sure if you visit europe much, but that statement isn't true. Golf is pretty accessible if you wish to play. I wouldn't comment on the accessibility in Asia as I'm not familiar with their situation as it pertains to golf.
Secondly, yea stuff happens after soccer games in europe just as it happens in hockey or other sports, but that's not the topic. Golf fans are the main subject here.
I don't think Poulter or anyone else's personality justifies being insulted at first sight. It's just bad manners. Period.
Haha,
One more thing I'll add to this discussion is that alcohol is sold at Euro tournaments too, but you'll seldom hear any rubbish from their fans. They just tend to be more knowledgeable of golf decorum and well-behaved than their counterparts here. Maybe they consume their sh!t in moderation or can handle it better, but either way they show more respect to the game.
