I'd suggest that the set of words which are appropriate or inappropriate are strongly dependent on the writer, context and the type of writing, and attempting to impose a single specific set of words as a privileged set of appropriateness/inappropriateness is indeed simply imposing their morality on everyone else.
In many cases they are making a false assertion that a particular word is inappropriate, simply because it's inappropriate for them in their context/culture/morality while it's entirely appropriate for the writer's context/culture/morality; and those false assertions essentially attempt to change the writers' own notion of what's appropriate or not towards what Google considers appropriate - and I don't agree that Google should be allowed to apply such social influence.
