True. And a warning

Once, when I was teaching at an institution that bent over backward for foreign students, I was asked in class one day, “What is your policy toward foreign students?” My reply was: “To me, all students are the same. I treat them all the same and hold them all to the same standards.” The next semester there was an organized boycott of my classes by foreign students. When people get used to preferential treatment, equal treatment seems like discrimination.
