That was a pretty stupid remark for him to make, but can we please stop firing people for their comments and opinions?
Firing people for their thoughts (as opposed to the value of their work) doesn't fix anything. It just creates a culture where people say one thing and believe another.
It's sort of like the idea of kicking Trump off of Twitter. Doing so wouldn't make him a better president, it would just reduce the visibility of his grotesque thought process.
