The result from HR was silence. He never intended for the memo to go public, but he did want feedback from his colleagues. If HR didn't want the issue going further, they should have actually responded to him.

But he saw a problem and wanted to fix it. You're basically saying he should have left the problem where it is and pretend itsr not there, which is not what engineers typically do. Can you blame him for that?

Not just engineers...That kind of mentality does not advance society.

Imagine..."She thought black people should not have to sit at the back of the bus. She told authorities who just remained silent. She should have sucked it up and moved to the north!"
