Applicants are very well aware when residencies are hiding things from them on their websites. Here are other examples:
Duke:
http://residency.medicine.duke.edu/our-residents/current-residents/2014
Vanderbilt:
https://medicine.mc.vanderbilt.edu/residencyprogram_residents#pgy1residents
even Wright State:
http://www.med.wright.edu/im/res/residents
all of them list the medical schools that their interns/residents attended. It's just common protocol as all of our home med schools in the United States(that all have residency programs) have the same listings.
You're right, I never stated directly that "there may all very well be foreign because UTH doesn't post the schools on the list and that is a red flag for mostly foreign", bc most people have some level of critical thinking and analytical skills and don't have to have literally every thought be SPELLED OUT for them. You wrongfully assumed that my reasoning behind posting up the roster (with no medical school listed -- an automatic sign) was bc of their names and skin color. You rolled the dice, you bet, and you lost. So now you're backtracking to say it's only natural to assume that bc I didn't state every single thought directly, that it was racism/bigotry. You weren't the only one, but that doesn't make you any less wrong. As an aside, if you look at the pictures on the UT-Houston roster closer to the bottom - they look more like passport pictures as well, which also points to it as well.
Rightfully or wrongfully, AMG applicants who see a program roster list of nearly all IMGs (or those who try to hide that they are) in a program will wonder why this is. Especially when you have another medical school in the same city which has NO IMGs and lists their med schools directly.
So the natural question every AMG is going to ask is why is an American medical school with an IM residency program not attracting AMGs in huge numbers (esp. it's own med school graduates) and why is there another residency program in the same specialty in the same city that is able to attract AMGs in huge numbers.
I would ask the same of another IM program in the same city that's not with UT-Houston or BCM, that has an "affiliation" with Cornell:
