Just give it another 10 years man, you'll mellow out a bit, if you don't end up giving yourself a coronary by then.
You're going about this all wrong. There's nothing unique about you ya know. You're not special. You don't have anything more figured out than anyone else ever has. Theres been millions and billions of young people with no life experience and big ideas going back over decades and centuries and millennia. They all came out of childhood, peeled their eyelids back just enough to get a tiny glimpse of the real world, figured they'd seen it all, identified all the problems, figured out all the solutions, figured everyone else who didn't come to these same conclusions was some archaic "old", proclaimed life to be not fair and declared it never would be fair until everyone viewed it exactly like they did.
Guess what? Life ain't fair. Get over it.
Yelling at the world, shaking your fist, and proclaiming everyone who doesn't see things your way as some retrograde knuckledragger will get you nowhere. If you knew anything about human nature at all you'd know nobody will give you any credence acting like that. All.youre accomplishing with stuff like this is pushing them away from your ideas and entrenching even more firmly in the ideas you are against.
You need to be inspirational. Set an example. Humans are emotional creatures. Even the ones who claim to be all open-minded and rational and shit. People have to feel good about whatever idea it is you're trying to sell or they're never going to latch on to it.
Some guy who don't even have to shave his whole face yet yelling at the clouds like some disgruntled senile old man about how life ain't fair is most certainly not a successful path towards the acceptance of your ideas.
