I'm not particularly straight or racist, but I am the rest. Why do you ask ?
This sounds like the kind of rampant generalization that astrology and similar stuff puts out. 15-25 sounds really specific but it actually covers a huge amount of the internet population and certainly covers the most diverse group, from teens to adults. The difference between say 40 and 50 isn't a big deal, but between 15 to 25 its VAST. Middle-class gamer is a pretty safe bet on the internet, and certainly gaming sites know that, and ditto non-religious. . The racist thing again sounds like its magically reading your mind, but race is a sensitive issue everywhere and the little niggle of guilt thats attached to it rings through because I think we are all scared and unsure if we are racist. Straight is just playing the percentages.
Most tellingly, we ALL like to think that we are above average intelligence. Sadly its not true, but EVERYONE thinks they are above average. And we all know that to some degree we are underachieving. Because everyone slacks off, and definitely someone in that age bracket and... say ... browsing the internet instead of doing something worthwhile is...
I suspect that the description will get a hit for about 75% of the escapist. I know im on the older end at 24, but there are some older, some girls, some gender benders. Btw if you are the last one, we should start a group. I know there's a few gay/bi guys here and I feel we are being underrepresented in the gaming world! We should protest and stuff!
