Personally, it's because I look at what a jackass I was at that age. I don't spew a lot of hate, but I'm definitely going to keep an individual's age in mind in any encounter. Sorry, guys, but as 'mature' as you think you may be at this point, you're really not. It's just that simple. When you're eighteen you'll be better, but still pretty dumb... 21, even better, but still dumb... We'll see you around 23 or so. Then, you too will be hating on the young 'uns running around like they know everything. Just remember... We may be dismissing you as ignorant and immature, but we ourselves were that way once, and underwent the same prejudices, for the same (completely valid) reasons.
