What's amoral in that?

Culture and traditions don't come in 200 ml bottle sizes with suggestions of what they go best with, leaving the mixing and matching to us. They come in whole specific-brand supermarkets, where it's kept all in the same family. It's a whole Universes that's all contained in and you have everything you're supposed to need, if you follow the rule book to the tee. Anything else is treachery, that we spare no expense crying about. We chastise, traumatize and cull anything else—what we otherwise call moral policing. 

The treachery is inevitable when old ideas meet different ones. Unless we're busy getting enraged about it and screaming treason, cultural interaction is an ongoing experiment in which the older habits die hard, if we let them. Over time, our ways solidify and become tradition which becomes our ways which becomes our culture. It is a spectrum that goes from mild to hard core, with the hard core section inscribed in stone. It's artfully etched so that it remains untouched for future immemorial while calendars, clocks and times evolve, for better or worse. It includes everything that is excluded from being the experiment that is interhuman interaction at all levels. 

As with everything worth inscribing, it also draws the line separating what that community should consider good and bad, right and wrong, and nice and evil. In other words, hard core culture defines our morals. And as we learn, what is one culture's fodder can another one's poison. 

An essentially harmless habit, though practiced for decades, can be demonized because another group of people never heard enough about it. Their whole Universe consists of the few that's theirs as they live in total isolation from awareness of the many other ways, good or bad, of the people, right next door. With lack of competition and reference, there's a big chance that it becomes their effective God, especially when it's confronted. For example when a marriage conservative society sees an unmarried boy and girl together, a similar society sees a girl with short clothes or when they see people beyond their "marriageable age" still single and unconcerned, an isolated culture could observe and live and let live. 

Their culture, being the spectrum that it is, didn't require them to care till they were confronted about it. For the same reason, their meter read that something was out of range and blew, as did their minds. The spectrum doesn't allow general rationalised thinking that maybe there are other worlds out there whose internal reasons to follow their own lifestyles are as equally irrational as theirs, to which the ideal response is to be curious. But when it becomes their God, it becomes sacred which anything but only that is taboo. And if the people are isolated enough, it can be taboo enough to discard basic things like humanity, decency and respect, all in the name of culture. 

What happened is that they never looked out to their window, were left with a cultural view that didn't add up, didn't abandon their culture God nonetheless, turned a warped idea that defeats regular humanity into a well accepted moral in their circles, the warped morals did the damage and we now have officially dehumanized people, all in the name of "culture". Top contenders of this phenomenon are (things that eventually end up as)woman-adverse and restrictive views, honour killings and female genital mutilation, among many others. 

It is safe to say that humanity can go backward as much as it can go forward and make its resources of advancement a complete waste. Generations can get stuck in a rut because the old people become kings and queens and make the rules. They only last till the people they oppressed with stale thinking became staler with it, start leading the pack with it while they also do their bit to head the free downward spiral of society. 

We need to remember that the next time we call someone out for obtuse morals, it's time to open the window, let some light in and educate ourselves about the different kind of people we are around. Ask, "So, what's amoral in that?", before you go to town condemning them. If we assert our right to be ourselves, they should be able to assert the right to be themselves. If we are concerned about dying culture, we should be as concerned about the death and rot the same cultures were caused to date. We should also be able to interpret its effect (good and bad) in terms of what it does to humans per se, regardless of country and tradition. 

We're human by Planet Earth and biology. Being from a different culture or tradition doesn't change any of that. Being ignorant about the science of it and trumping our cultural and traditional pride over it, eventually ruins our chances of general human happiness. The other thing is that if you want it to be alive, the benefit is what you give yourself. So, go ahead and make it so. Why would you beg for it from someone else?
