It's not that, I'm just not sure what's more "ignorant"... Not agreeing with someone, or calling someone "ignorant" for not agreeing with you. And you're right. I'm 36 years old, I have a business to run, and the last thing I have patience for is some teenager losing their temper and calling me names over a stupid disagreement in a matter that's so damn inconsequential that what I ate for breakfast is more important.
If it makes you feel any better, I have a different perspective on life than you because I do more than flip burgers for a living and argue stupidity in forums.
Now please. Grow up, act your age, get some kind of life where the amount of memory on a card really isn't that significant to you any more and stop pushing.
