Re: Please repaint Darth Vader in different color
...which demonstrates how ingrained our prejudices are from our cultural upbringings:
Pink is for girls, blue is for boys, black is bad and white is good etc.
If you're irritated by this insignificant policy change (that makes no difference to the operation of the NCSC) then you're one of the fortunate ones!
It's an innocuous change that's (probably) not going to make any material difference to you whatsoever, but it does go some way to help bring some relief to other human beings.
If you really do think that this is a big deal, try not to worry so much. That's a first world problem and you may be in need of some introspection to discover why you feel so strongly that this is somehow outrageous.
You just might not understand the problem that this is seeking to address....and that's precisely why it isn't necessarily a bad thing.
