> If you're having a high level technical exchange with somebody that you don't know, then you find out that that other person is a female, you're really impressed, that a girl will be that good at this very technical topic.

What nonsense is that? I've never noticed any correlation between gender and technical skills. I mean, I've noticed that there are fewer women in the technical space, but not that their skills are lower.

You then seem to go on to assume all white people are racist against black people. Because both of your examples are racist.
