I think it's a forum for people to discuss ANY topic reated to games (this is a games website is it not?) and unless a topic is initmidating, threatening or is used to degrade other users it is all good. I don't care if you post Playstation is bestest or Xbox rulez because.... or Join the PC mazter race etc. You absolutely are not forced to read or respond to them.
In fact, I would argue that bitching about such topics is as bad as posting them, if there was such a thing as them being bad. I even had the choice of either not voting or even participating in the discussion which I could do for ANY posting on these forums.
Oh and BTW your example of whether DRM was good or bad is as valid a topic as you'll find on these or any discussion forum. That topic absolutley had to do with EVERY gamer and the overall directiojn of the industry.... SO if you really would like to make a valid argument perhaps you could start by usign appropriate examples.
