This site is interesting. With or without cynical arseholes.
If you want a site with perfect, polite, constantly evolving, hospitable users, then go to sleep. Dreaming is good fun.
This place is open to the whole internet world, you have to accept every website is going to have their version of the arsehole. You can try hunting around but we promise you won't find too many places more intersting then here.
The amount of enjoyment you have here is directly related to how you look at things. What you call an arsehole, we call humor. We see the light side of a smartarse remark and thus don't take it seriously. If someone says you have a crap username, laugh it off. People judge what you say, not what you're called.
Yes, yes I am a Guru
...and I'm Chuck Norris too but shhhh.
