Sarcasm is usually used when someone has disdain for whoever they're speaking to.
You're a strange cat. Most people find this place looking for specific information and usually stay because they like the vibe. You on the other hand, seem to equate this with a social-networking place for teenagers and people in their early 20's, like yourself. Why are you here? Bored with MySpace and Facebook? Why waste our time and bandwidth?
No one seemingly, except for you really gives a **** about the color choice of the forum template. Most people are here because they've found what they like in life and are not really concerned with posturing or being antagonistic. Your posts have been self-serving and counter-productive to any sort of effective discussion. Are trying out for internet rock star or something? Not gonna get a lot of play here, no one cares.
Again, people here are willing to engage you if you can relate to them on a regular level. No one wants to deal with someone who puts their confrontational personality first and their interest in cars second. I can't take you seriously when you choose to put Eminem as your avatar when most guys choose their pride and joy. Tells me your priorities are somewhere else.
Perhaps when you figure out what's important you'll change your tune.
