Man, you seem to have a very strong myself vs. the world type of approach to this website. I think it's a bit of a shame because you chiming in on skate shit is growing on me; even when I don't necessarily agree, I like the sharp wit.
This is a different matter though and while I get what you're trying to convey, and the good intention behind the shock value, I can guarantee you that the human brain is more complex than you seem to think (on the sole basis of what you expressed), and I think you have to understand that some key logic or cognitive abilities that are so elementary and mundane, yet so crucial to people not suffering from certain mental conditions are legitimately impaired in the people suffering from them. You can't force synaptic connections into those people's brains; actually, their brains missing them constitutes their very illness, so they'd probably be thankful if you could equip them. But words aren't direct chemicals. In most serious cases, you'll just hurt people who've been hearing the same tired motivational speech by strangers their whole life, get the gist of it way more than you assume they do (or than you even do yourself), but just can't help but witness the persistance of their physical inability to function the way they would like to.
Obviously everybody likes to publicly diagnose themselves this or that nowadays with varying degrees of justification, but that's no reason not to take mental handicaps lightheartedly. OCD killed Joey Ramone and I'm sure keeps devouring many others to this day; don't let your mind slip distracted by the noise of the kid at the park who claims every of Reynolds' tics for anonymous attention. Of course a lot of people do need wake up calls, but if you're dealing with someone with an actual disorder then your voice isn't getting anywhere ever, and you'll just be another pain to them.
