I am sorry to say but you’re observations are not accurate… or even relevant to the topic. Being namazi does not translate as inhumane, niether does it work the other way…i.e. be-namaz = inhumane. Humanity is not exclusive to one culture over other…so that is a moot point.
Think of the bigger picture, where if namaz is a standard by which if unobserved, renders useless any other good actions you have performed as a muslim. In this world youre action might count for alot, in the next, you’ll have very little to show for. And like it or lump it, that is what really counts.
Its one thing if you’re ignorant about the signficance of namaz, its another to dismiss it altogether.
