I'd venture a guess that you don't go around telling people to ♥♥♥♥ their mothers when you don't have a screen to hide behind, or that if you do the majority of people let it go because you're fifteen years old. If everything you've said is true, you might be an intelligent individual. If you think that grants you worth, or makes your opinion valuable to anybody but you, you're wrong.
Being fifteen means you've never had to take care of yourself. You've presumably never known the fear, loneliness, and pain of addiction. I sincerely hope that you never do. Everything in your life right now, you can afford to take for granted, because you don't actually have to work for anything. It's handed to you. So here you go, attempting to prove how smart you are, to a stranger on the internet, because suddenly just being you isn't enough to impress.
While I could do a point-by-point analysis of why your self-aggrandizing diatribe is meaningless to everyone but you, it would essentially feed your ego further to dissect your message, which was the whole purpose of writing it out in the first place. Your IQ proves nothing. Your bronyism proves less than that. Your self-reported physics knowledge is likely ♥♥♥♥♥♥♥♥, but also useless in forming human relationships.
Being a ♥♥♥♥ on the internet is easy. Actually being thoughtful, considering other people before you say things, and being willing to admit wrongdoing or at least try to examine a perspective besides your own, that's a task. But you can get away with just being a ♥♥♥♥, and it feeds your sense of superiority (which clearly you possess, by the nature of your defense), because you can't defeat irrational insults with rational responses. So what do I think of you? Again, if what you said is true, you're an intelligent person, sure. But I think your casual willingness to be mean-spirited to people you don't know, who are gathering in a virtual space to discuss things that are important to them, outweighs whatever intelligence you have and makes you an unpleasant person to interact with. It would do you well to consider others, and also entertain the notion that you are not better than other people.
Complaining that you are downvoted when your "advice" (the pedestal you built for yourself) is irrelevant to the thread you comment in, then being an outright ♥♥♥♥♥♥♥ when someone explains that downvote -which didn't need to be explained at all- is confrontational at best, but in reality it's just dickishness. Which no one can prevent. But it's not something people have to put up with either.
I feel like I've just wasted my time, because I think you are more interested in defending yourself than examining and discussing.
