Out of left field question. 

Are people cool with me using other player created races/human variants as characters in my nation? 

Hard question for me to word but id like to show the diversity of the not!USA.

And I know some people like to horde and say only mine or that this ethnicity will not kill this one etc etc but irl, USA Muslim soldiers fought Muslim soldiers in afghanistan/iraq with valor. In Vietnam, ethnic USA orientals fought fellow orientals with valor.

Just curious, I just feel having all generic white guys to be bland.

Thoughts? Care?
