Anyone should be free to whine about anything like this. I mean, if you don't like what your company is doing, complain. If you still can't take it, quit. If they get enough complaints in the company, then they certainly don't have to publish him.
And otherwise, if no publisher wants to publish him, that's fine. That's their right - they can still self-publish if they want to get their word out. If someone does, that's fine as well. As long as the book itself isn't itself full of hate speech and the like, then any publisher should be free to publish it.
He will no doubt get published,, he's very marketable despite the negative baggage.
This is more about some employees at the shop having to work long hours to promote an author they find disgusting.
