I'm sorry if this was ambiguous. The analogy isn't about death or how one dies, it's about what's "proper" and what isn't.

People will always try to silence dissenting opinions by arguing it's not the proper time to voice them, that one should wait a while... until we have changed subjects and whatever you had to say can't even be heard anymore, that is.

We shouldn't care about "proper"; the death of an author is an excellent opportunity to discuss his work, for and against, just as the effect of a policy is an excellent time to discuss the policy itself.
