Perth, I'm your counterpoint. You described me pretty well with "I was impatient, intolerant, arrogant and basically everything your machoman stereotype conjures."
As I got older (matured) and wiser (209 on the hell test) I didn't like me, so I evolved. My ex went out and found the type I had been, but that's OK. I like me better now. I can't go back.
As for the article, he makes some good points but blows his credibility all to hell with some outrageous claims.
