Clash we do...though we have it in us to compliment one another through mutual undestanding and respect, something all civilizations wish to posess,we humans chose instead to go head on and lock horns.
Who benefits? Certainly not the law abiding innocents! Though I would say we each may have at some time or another,knowingly and/or unknowingly, played into the hands of the degenerates posing as noble guardians of civil society, and contributed to the mayhem and clashes.
