A lot of what you say can be applied to other, non-religious cultures, not least that of the west, albeit in different measure. Any society will develop an overarching system of rules and standards; it's necessary to avoid anarchy, which is more inimical to the broader progress of mankind. People naturally band together, it's an evolutionary trait, so regardless of what intangible strictures those tribes are subject to, there will always be friction between and indeed amongst them. Voltaire said "If God did not exist it would be necessary to create him." and he was dead right, he just didn't mean 'God' in the strictly theistic sense.

Ultimately, people are people, meaning they need reeling in or things go to shit. Perhaps there exists an ideal set of circumstances under which civilised man can live peacefully without noticeably impinging on his moral objectivity, but let's not hold our breath. As long as there are groups, there will be some cunts who tighten the shackles for everyone, whether it be by breaking the rules, or making the rules.

So yes, all religions are bad, but in the spirit of catching all, I'd go broader.
