I think you may be inferring a little too much about masses of people. Who is to say that one is trying to go for a specific image or style. Perhaps when a person states a differing opinion it is because they legitimately think it. I understand there is a lot of opinion exaggeration that goes on, but in a way I think it's part of the Escapist's image. The Escapist sees itself as the 'indie' game community. The game community that focuses on the underrated side of gaming. And while this image may or may not be accurate, it spawns a lot of people feeling the need to 'fit in'. The Escapist is a pretty tight knit community, and people want to get in on that. The whole image of being 'edgy' if we are assuming that it is purposeful, is often due to the Escapist's general arrogance. A large portion of the population believes they are highly intelligent and while I won't refute that, a large portion of posters are also 15 or 16, an age when one's opinion will not always be the same 2 or 3 years later. I'm not saying that 15 or 16 year-olds can't be quite intelligent, but there is a certain arrogance that comes out of ignorance at that age. I had it when I was 16, I still have some of that going on. I mean, I'm still only 19 I don't consider myself better in any way.
I frequently find I will have differing opinions to the majority on the Escapist. Sometimes I post angrily in subjects that frustrate me (ChromeAlchemist and Wordsmith you know exactly the kind of subject I'm talking about). Sometimes I will simply not post in order spare myself having to defend myself in the presence of an overwhelming opinion.
On a final note, I wish we would stop calling out 'older users' on being arrogant or elitist or grumpy obsolete whiners or what-have-you. Being nostalgic about the site when it was just full of your friends is not a crime. A year from now, if you still post on the site, you'll know what I mean. People just... stop posting. There is a very large chance that new posters will come on with the goal of being the next big poster and rack up tens of thousands of posts. etc etc site intraspection blah blah... I've lost my original point.
