Hehehe communicate in grunts? May as well, if it's proven the devolution is real I'm not sure I'd be very surprised.
I don't mind the words white, black, red, yellow, or green..because...well we are
White people have very light skin color pigments...white - peachish or so.
Black people have black and dark brown skin color pigments
Native Americans people have a kind of sienna brown pigment as well as shades of red.
Asians are ...well...yellow.
And mediterranean peoples (Italians mostly) have greens and tans in their skin.
I believe the language you use should really depend on the preferences of the person you are speaking to. Like..I don't swear around my mum 'cause she doesn't like it.
And to add to the "What Sucks" list...Someone was mocking my accent and the general fact that I am Irish. So I kicked him...hard. And I got fined for it. Gah...
