Tau=space Asians (or, 'spasians')
Space Marines=Galactic Aryan Supermen
Salamanders=as above, in blackface
Tyranids=Republicans from outer space
I mean, come on, one chapter in a million is black. If that kind of ratio of whites to non-whites existed in reality it would be called Montana.
Tau are so super that I have super non-stereotypical tactics when I play them:
Kamikaze!
Load all my shits into flying cars and
drive them straight into the enemy. Kroot must sit in the back!
Okinawa-Style Hide and Go Seek!
All Tau go ground all time! Great happy fun!
Sepuku!
When I lose to my 10 year old nephew,
whip all my Taus up against the wall in embarrassment and disgust!
Whatever. I didn't make Tau, I just play them.
