Sadly, the more you try to explain something most won't understand to people who have preemptively decided they don't want to understand, the more they'll use it to "prove" their point. Age isn't just a number, but it also isn't always a defining trait. You do have hyper-intelligent 12 year olds that go to college. They're not the rule, they're the exception. But they do exist. One can be rather mature for their age. I don't pay much attention to the stars here. In fact, I forget they're there most of the time. (It also helps that I don't post much, I only really lurk.)
Your posts both in the OOC thread and the IC thread have struck me as well written, well thought out, and well spoken. No, this isn't something that I normally attribute to people below the age of eighteen. But then again...
Wouldn't that make you the exception, and not the rule?
EDIT: In case I'm not clear, let me shitpost for a moment.
Nigga, you below eighteen but your posts ain't be shit. You'se a pretty cool cat; not a shitter. Don't worry about it.
