There are fundamental issues regarding character, integrity and common sense involved in this issue and while "mental illness" and the "availability/access to" arguing points have some validity it is the unpleasant fact that few want to admit, that we built the house we live in and if anyone thinks that pointing a finger at these nebulous rationales proves a thing, they should be living in Cairo because they'd be familiar with denile..
