Are Men @ssholes?

According to glamour magazine, roughly 16% of men are assholes (their words).

Even though the whole article doesn't seem all that scientific, I could see this being accurate.

Here's the signs that a guy may be an asshole:
1)  He only wants sex
2)  He's a chronic drunk dialer
3)  He texts and bails
4)  You're always making excuses for him
5)  He makes you feel like crap

Now, in the spirit of protecting the guilty, I can think of at least one person's boyfriend who has an, ahem, perfect score on this.  I think #4 is especially true.  If one has to tell others that her guy is not all that bad, that pretty much says it all.  I can think of a couple friends, even, who might complain about their guys about little things and, ultimately, I think their guys are better than they get credit for.  However, whenever a friend goes out of her way to point out that her boyfriend is wonderful, I know that's the first immediate red flag.  I never trust anyone who goes out of her way to point out how spectacular her boyfriend/relationship is or how incredibly happy she is.  Generally speaking, I think people who are nitpicking and complaining about little petty things are oftentimes in the ones sitting in the most enviable positions (both in relationships and in life) .  Tanget.  Anyhow.

Agree or disagree with this list?  Agree or disagree with this percentage of less than favorable men?  Anyone feel she's met all 16% of them?
