You just described the majority of teenagers, whom probably fill 90% of this site. You also described a good portion of spam in particular, femininity aside, who reside in spam in most cases to get 'something off their chest' or use it as a 'closet of sorts' for their angst against things on the outside world. Congratulations. I would suggest that instead of judging a specific individual, that you try to understand them. However, this is spam and it will, as in all things spam, remain convinced that it has something better to offer.
Actually agree with you a bit but the delivery obviously is turning people against seeing your point. Also id temper it with the fact that spam isnt always that close minded, and when it is its either part of the tough front or down to the same inexperience that causes the angst you mentioned.
There's never a point to painting all of spam with the same brush, either.
