Is a logical opinion a thing?

There is a difference between a conspiracy theory the Conspiracy Theory fallacy. Person 1 is certainly wrong by claiming "it’s only a conspiracy if it’s false" as they just don't seem to understand the definition. But person 2 appears to be engaged in Equivocation by switching from the conspiracy theory to the conspiracy theory fallacy. If the video did, indeed, commit the fallacy (see the link) then this would be less of a problem for person #2.

I don't know what "One day we will have the truth to finish the logic. For now we can only have a logical opinion" is supposed to mean. Seems like a misuse of "logic" in general. Perhaps one day we will have all the facts and be able to confirm or debunk the theory (if not already), but we have more than just opinion now... we can still follow the evidence where it leads (via the reasoning process). If one wants to label this "opinion," fine, but it should be make clear that all opinions are not equally reasonable.
