We need to teach our students that the employment they take doesn't exist in a vacuum. Your choice of employee can impact not only yourself but the wider world. There's more to life than intellectual satisfaction.
Teach your values to your own kids, man
> leave moral instruction to parents and other institutions like it should be.
Should be, according to what doctrine? It certainly sounds like you're attempting to establish institutional moral instruction by imposing limits on when and where morality can be discussed.
Why are we allowed to teach students astronomy but not morality? Go back further and we couldn't even freely teach astronomy. Do you remember Galileo's trial for heresy? Or Socrates' condemnation to death for "corrupting the youth"? This war for teaching the ability to capably assess ethics and morality has been waging before you, I, Hacker News, universities, the internet, the printing press...
If you don't think it was right to kill Socrates for simply spreading the message of critical thinking, then you have to accept that adults can organize to teach whatever they wish at universities, assuming it doesn't run afoul of Constitutional protections.
