How dare you to use a face! How dare you to use a building! How dare they use something some country specific! And even worst, generic! Oh no, a building of an institution!
No matter what is in, people looking to twist it in offense will find a reason.
Just take a look at Maldive's currency and tell me that this proposal isn't terribly boring.
I found faces more of uglier, but that is not the same as offensive. I dont feel insulted over the faces, they are just more boring to look at.
I think there is massive difference between "I prefer this other picture" or "this is ugly" and the "it is insulting and offensive" people do here.
For me, the 20 rufiyaa bill is the most interesting design.
