"Sexual orientation is a part of diversity and cannot be ignored, said Robert Anderson, chair of the Academic Senate of the University of California system.
It's for their own good. The university has services it wants to provide. All the government's intrusions into your private life are for your own good. You will be given what is good for you, so come on now, tell us all about everything.
ADDED: When I started college, at the University of Michigan in 1969, the freshman were all given a test — various multiple choice questions — and it produced a number of different scores, one of which was not revealed to the students (although we figured out the code and were able to read our scores). This score purported to place everyone on a spectrum from very masculine to very feminine, and perhaps the authorities imagined that they could identify the homosexuals.
What were the questions? — you may wonder. Famously, one question was do you prefer cooked or raw carrots. In my family, we only ate raw carrots, so I'd always regarded cooked carrots as gross. I suppose that made the University regard me as more of a lesbian. I seem to remember a question that asked what would you rather do, where one option was to take apart a clock and then put it back together again. I don't know what the other choice was, but I suspect that clock project skewed a lot of the boys gay.
