Well, passionate was the nicest way to put it...
I haven't heard him know about anything or have any sense anywhere else except in WoW. Yet he participates in discussions with his politically correct point of view in such a full and sure of himself manner, that it really shows how sad the situation is.
I generally find it sad when people seem to be interested only in 1 thing, and that thing is a fairy tale. Sure, they will have opinions about real life stuff, but those opinions too often seem to lack any real, solid, researched foundation. On the other hand they think they know more stuff than they actually do. And feel so prideful, and knowledgeable, and are so politically correct...
But in truth, these people are just politically correct about anything, just cause it's the 'right' way to think, and feel comfortable in that and just allow themselves the leisure of learning the lore of a fairy tale, in detriment of learning what real people did in this real world. To get to this point... for me it's sad.
