The sun is the center of the solar system
There's a huge difference between being civilized and being just plain short-sighted. When a person says something about anything, a normal person in his right mind would take the comment and respect it. Why? Because it's his basic right. The least you can do is respect it. In a healthy, friendly conversation, when one disagrees with a comment, there is no better way to vent your side than to declare and reason about whatever it is that you think. That way, you allow other people to reciprocate the respect.
It's a stupid, coward's way out to keep quiet and keep grudge just because somebody else didn't aggree with what you think, or follow what you say. More so, it's just so dense to hold on to that grudge and then run around telling everybody about it while keeping that person in the shadows. It's just not the way to make a good impression of greatness.
You cannot order people to think or act the way you do or the way you want them to. Stop disappointing yourself and placing the blame on others. The name of the game is respect and it's so sad for you because just like everything else in this world, it is earned and not ordered. It's just how things go in the real world. I hate bursting bubbles but the center of the solar system is the sun, not you.
