Well, on the other hand, you as a father/mother can show your children all the other aspects, you can teach them respect, love and tolerance, and the most important thing, you can and i'm sure you do Love them unconditionally!!
Of course it's hard for children to engange all the cruelity and hatred out there, but if they have someone to rely on,with a stout heart and faith in humanity, they won't take that much damage at all. If you are the truth-seeking person you say you were, you cannot deny that love is everywhere around us, and only because "they" pour oil in the fire of the peoples "dark" side, it does not mean that the greater part of us wants the things to be the way they are.
It is important for our children to learn the truth, even if it might be a frustrating one, so they don't become blue-eyed dreamers who are totally off the road the first time they get in serious trouble, nor should they become depressed and faithless. It is in our hands what we teach our little ones, and in what condition we leave our planet behind for them.
Don't be depressed, you know there's a whole lot of people out there who CAN do better than this
