*sigh* I wish I knew...
I've always hoped that people will someday come to the realization that we're living for a common goal, and that selfishness, fear, ignorance needs to stop. Religions have been created for the purpose of governing nations, attempting to change the ways of civility, and to open people's hearts to the world's beautiful mysteries.
I feel, personally, that each and every religion with its root in love/understanding has merit. People will always have view things differently, as ChrisP said... so we'll never actually attain a global peace or understanding. Dismal as I make it sound, there's hope for the people who want to make this world a better place irregaurdless of religious or non-religious prefrence. We're all trying to make this life, and make it worth while.
I wish we could all just wake up from our ignorance and live how we're supposed to, with love in our hearts for everything, and an inquisitive, child-like mind. Find our common ground, and just be.
... i should really stop smoking the peace pipe *smiles*
