Hi Crypts
It's not so much that what you say isn't important, but rather the people you're interacting with seem to be the problem. When we're surrounded by selfish people it can make us feel like we are the problem, but that's a wrong perception.

And as far as the kind of people you find online, such as facebook, it's not even worth thinking about. The world is full of people eager to tell you you're wrong. Not just You, but Anyone they disagree with.

People no longer discuss, debate, listen. Now people inform and if you don't accept their words then there's something wrong with whoever they're talking to. We all have dealt with it. I quit interacting, or limit how much i do, to avoid such people. Things are much better now.

Don't let the blowhards of the world convince you that you're less than.
