I guess I better define who is Us and who is Them.
1) Us=Atheists and Them=Christians
2) Us=Americans and Them=Non-Americans
3) Us=Americans and Them=Middle-Easterners
4) Us=Americans and Them=Chinese Communists
5) Us=Blacks and Them=Whites
6) Us=LGTB folks and Them=Religious folks
7) Us=Democrats and Them=Republicans
8) Us=Northern States and Them=Southern States
I could go on and on and on, but I think you get the idea
In light of this illuminated idea, read this article: http://www.tmt.org/news-center/china-joins-thirty-meter-telescope-p...
In Science there is no Us vs. Them!!!!!! There is not Spanish Biology and Canadian Physics. The only science called Biology there is is what all humans have worked together to understand what those same people categorized as information about Biology.
