Not sure there's much conscience in Banksy making anti-national chauvinist memes whilst not identifying as any sort of nationalist, but there's even less in dismissing all criticisms of one's own society's treatment of, say, women because some other societies treat them worse.
For all that I don't think posturing graffiti artists are the saviours of humanity, it's difficult not to notice that the groups that actually are tackling FGM are practising Muslims and super-liberal NGOs (in that order) and that the people who raise it to deflect from criticisms of their own society are not represented at all in those efforts. Or are actively campaigning to get women's escape routes from those countries shut down.
Can't really lecture others on losing their sense of perspective about the magnitude of injustices either when a week ago you were expressing outrage at checks post history creatives depicting certain characters in LOTR as non-white!?!
The moral posture you're criticising is not actually a thing, I personally don't know of any Western intellectual who criticises the West but is fine with FGM for example. But it seems that the fault you find in them is that when they criticise the West, for example, they don't also add a list of grievances against all the other countries (but surely they'd have to speak for 10 hours every time they open their mouths?).
It's also funny how you take the 30,000 Iranian civilians killed at face value, but don't talk about the wrongs of the British empire. And you didn't even mention North Korea once. You see the issue with your reqs?
Or maybe, we should look at the problems in our society and try to make it better, instead of just shouting into the void about things we, as nations, can't and wouldn't be and perhaps, shouldn't able to change?
Art will always be about speaking truth to power, and that power will usually be the one closest felt. There's not much value in a swede speaking truth to Nigerian warlords.
