I actually tend to mostly agree with you on this. I think the safest and most rational policy is just to avoid discussing sensitive topics at work so as not to risk creating a hostile atmosphere, and I don't consider this an unreasonable restriction on freedom of expression. Talk politics and immigration with your friends and family, not your teammates at the office.

My problem is that Google as a company, at least as far as the Mountain View campus goes, apparently disagrees. My understanding -- and it's possible I'm wrong -- is that Google supports and encourages openly discussing a variety of topics at work, and the internal tool he used to publish his memo was designed and used exactly for this purpose. (What Googlers apparently describe as "an internal-only Reddit.") If this is true then he was fired not for discussing inappropriate topics, but for holding opinions the hive-mind finds disagreeable.

Either you as a company support discussing sensitive topics in the office, or you don't. If you don't that should be made clear and enforced equally for everyone. If you do then you can't pick and choose which opinions you approve of based on what's popular, and expressing a dissenting opinion should not, at the very least, be a fireable offense!
