One of the toughest things about discrimination is being able to prove it. I'm a white man, but I spent time living in Japan where I was an obvious minority.

Some situations were clear to me that I was being treated a particular way because of my race. But then others were not so clear cut.

For example, one time I was talking in Japanese with a group and someone kept repeating what I said like "He said...". I was getting angry at that as I took it to mean that they were basically "translating" my Japanese for others. But then later, I was watching a Japanese TV drama and the same thing happened on there (with only Japanese speaking). That made me think that maybe this was just a cultural thing that people do and didn't have any reflection on me personally.

Having mentored a female engineer, I've seen that if you are constantly on the lookout for signs of discrimination against you, you will find so much of it. You'll go crazy thinking the whole world is out to get you because of your sex, race, etc. It's tough because there are no doubt situations where that does happen. But there are also situations where a white man would have been given the same feedback or treated in the same way. As a minority though, you only have your own experience to go on. It becomes tough to recognize what is legitimate discrimination vs what is just ordinarily communication.
