The thoughts you espouse are good ones-however if there was no suffering in the world, how would we learn compassion?
If there was no wrongdoing, how would we learn to choose the higher road?
People have pondered the things you speak of for millennia-however I would venture that those who would destroy others for their own gain are fewer and further between than you might think. True, most who are disposed toward such behaviour are narcissistic and self important-and hence end up in politics or some such field, directing the conflicts we see in the world around us-but the majority of people understand that, by protecting others we are, in a sense protecting ourselves.
Shows like MLP are an escape from the realities of day to day living. That's why I have exhorted any who would listen to protect the things that make them happy. The world is more than happy to rip your hide off, and to trample underfoot the things that you hold dear-so be careful who you share them with. It's not necessary to tell everyone everything about yourself-in fact it's foolish to give others that power to upset you. Rather, share with those who you trust-and who you think might enjoy it themselves.
I've walked the road a while-and I'm here to tell you that the things that make you happy are precious. If this sweet little show has found a place in you, guard it-and guard your friends who enjoy it too.
