Drunks go to the pub? Some of them. My understanding is that most true alcoholics drink by themselves though.

Certainly some people take gaming to excess. If it wasn't gaming it'd be something else for these people though.

People are mistaking cause and a symptom, too. Excessive substance abuse is a symptom of someone's problem, not the root cause of it.

It's not "World of Warcraft destroyed his relationship", but "He used World of Warcraft to destroy his relationship".

Controversial indeed :P

Attempting to argue that games are more destructive than anything else that easily addicted people spend their time on is perhaps misguided though.
