Thank you everyone, because there are many right answers here I have decided the solution is to stay away from dividing the clan into geographical or language divisions.
After asking my right hand guy who’s multilingual to get the scoop on this privately from some of our members (per the advice from some of you here), the feedback is amusing.
Archie Bunker is just not a white middle aged man at 704 Hauser Street. He’s a handful of brown teenage Peruvians, two 30 Somethings in Mexico, and a 28 year old woman who’s parents were from both places but lives in Rhode Island. They’re just as half-heartedly prejudicial as your typical isolated unworldly American. :smack: Im not entirely naive and know prejudice is universal but sort of was under the impression the rest of the world was super PC and Americans are just trying to catch up to be proper. This small sampling shows the opposite. 
Fortunately, first person shootem ups (in this case it is Half Life, CounterStrike, Left4Dead, and COD) are more important to them than digging on each other too much about their differences (which reminds me of a recent Cecil article on why video games are good for us).
So, in the end, Ive* quietly assigned* multilingual team leaders to keep everyone on the same page regarding practices, matches, etc - but not segregate everyone into groups based on those things. It’s going to be fun to see the Polish guy teamed with the Mexican fighting the Peruvian and Canadian.
Without labels and divisions I think it will force everyone to learn each other’s time zones and language a little better. And I really want to know what they’re saying in game without copying and pasting it later for translation.
I appreciate all the insight Dopers bring to things like this, and thank you. (I couldnt just rely on answers from partially anonymous gamers on the internet - without first asking for advice from partially anonymous think-tankers on the internet. :D)
*As an aside, some of you may be surprised to learn how much respect and “awe” that many younger foreigners have for our Marines. My clan was founded by a US Marine over a decade ago and has quite a few US miltitary servicemen from different branches involved (all people are welcome, military service isnt a requirement). This grew outward over time so we have servicemen from the UK and Canada (who knew that Canada had such a thing?) and our clan handle is a close approximation but universal variation on the Corp’s acronym. It’s just very cool to witness over my 8 years as an admin the dozens and dozens of non-US players who want to check us out first because of our American based military roots, and respect for US Marines. It’s even more notable to witness people’s private prejudices and quirks get kicked to the side when they play together (except for the occasional in-game taunts) and take real interest in each other’s life experiences. Gaming is indeed good for us. *
