Huh? There were two "western" caucasian couples on TARA1. And one half team (Howard). Everyone else was Asian. And yes India and Sri Lanka are totally part of Asia. Indians and Sri Lankans are officially caucasian by race but they are also Asian as they live in Asia. And people from those countries were just as eligible as "oriental" Asians as far as TARA is concerned. And there are many caucasians not only living in Asia but being born there as well plus many people of mixed race background. TARA needs diversity just as much as TAR does.

And TARA2 had just as many non "Asians". Marc and Rovilson refer to each other in their official AXN bios as "Aussie" and "American" so they are not 100% Asian pure. Henry is Afro-American. Paula & Natasha were at least part Australian and definitely looked 100% caucasian. Aurelia was French.

As far as "non-caucasians" on US TAR, I'm the first to complain it isn't diverse enough. But there have been a decent spattering of minorities which can include latinos. They are also caucasian though they tend these days to be lumped into another grouping where people mix up ethnic background for a race. Even people not named Lou Dobbs. Then there are Semites (Jews and Arabs) who sometimes are considered caucasian and sometimes are considered anther race by various people.

So other than white caucasian Christians or secular, non-believers who came from a Christian heritage, we have:

TAR1 - 2 black teams, I Jew (Drew)
TAR2 - 2 black teams, 1 Jew (Gary), 1 latino team
TAR3 - 2 black teams, 1 Asian (Kathy), 1 Jewish team (Teri & Ian) plus 1 individual Jewish racer (Zach - he won)
TAR4 - 1 black team (Least diverse season ever, yet another reason TAR4 sucked)
TAR5 - 1 black team (they won), 1 ethnic Armenian-American team that were both born in Syria (yes that is part of Asia too)
TAR6 - 1 black team, 1 Jewish team, 1 latina racer (Maria)
TAR7 - 1 black team (they won), 1 Arab-American (Alex) and I think Bianca was latina or partially so
TAR8 - 1 black family appropriately (cough) named The Black Family
TAR9 - 1 black team, 1 latina team
TAR10 - 2 black teams (one of which were also Muslim), 2 Asian teams (remember, India is part of Asia)
TAR11 - 1 black team, 1 Asian team, 1 latina team plus a couple of others of latino heritage (Rachel and I think Lorena too)

There may be others but this is just off the top of my head.
