You're replying to to a WoW.com blog post about gaming addiction.. on the internet. And poking fun at others no less ;)

Re-evaluate yourself before replying like that.

That is an ad hominem attack. Pick apart his argument all you want, but being dismissive of his argument because of who is saying it and where it is being said is not fair at all.

Yeah, it is actually possible to play WoW, read and reply to posts on WoW.com, whilst not being addicted and maintaining a healthy, responsible attitude to the game.

Drag's point seemed perfectly appropriate to me; if it seemed like it cut too close to home, maybe you should re-evaluate your relationship to the game.

Drag's comment was deliberately confrontational, insulting, and without any foundation. In other words, a 'troll'.
An ad-hominem counter is therefore entirely appropriate, if a little guilty of 'descending to his level'.

"Drag's point seemed perfectly appropriate to me; if it seemed like it cut too close to home, maybe you should re-evaluate your relationship to the game."

That ^

Also, not a troll. I was serious about the second part, joking about the first. I think it's very, very amusing how everyone in this article's comments is defending their beloved game like they do.

It's just a game, and to the people who take it as more than a game, everyone should be happy that someone wants to help them.

"An ad-hominem counter is therefore entirely appropriate"

I don't mean to rip this quote out of context, but... really? I can't think of a case where it would be appropriate. The indication that you can't consider the other side without being immediately defensive is a classic symptom of addiction. Just saying.
