It's my opinion that (most, many, or all) people would like to have
an extra $10 in their pocket right now. Is that an opinion, or

In my opinion, depends on the cost of getting that $10.00.

Don't side-track the question. The issue of cost was not raised nor was
part of the question.

Can an opinion never be shown to also be a fact?

That question remains unanswered.
