You're right of course. Charles Darwin could not have been unsure of one part of evolution without being wrong about all of it.
No scientist has ever put forth a theory without being right about every aspect of it. Newton was completely right about the effects of gravity....or was that Einstein?

No matter. I think your point is made very well. We should use this criteria to determine the worth of all ideas. If a person is wrong or unsure about any one aspect of an idea then the entire idea should be thrown out. That way our knowledge can only advance if we know everything.

Maybe that is not what you mean by this criticism. Maybe you only want to use those standards when judging the worth of ideas that you don't like. Yeah, I think that is a more accurate assessment of your tactics.
