Am I obliged to ensure observers have full access to context, to ensure accuracy in their forming an opinion?

you are not obliged to anything. If you care about the accuracy of opinion, you might want to provide full context

To everyone, one by one?

unfortunately, who gets what information is typically not under your control.

then I shall continue not caring about irrational responses.

make the context accessible, seekers of truth will find it. Don't care about the rest.

You sound so confident of this fact :) Please excuse my extreme scepticism.

it was almost a tautology. It doesn't mean that different people seeing the same data come to the same conclusions.
