Related Question: How do we handle questions based on incorrect premise?
Unlike the premise explored in the linked question - how do we handle a question where the question is completely valid, yet includes an incorrect bit of information (which makes no difference to the actual question or its answers)
Eg. Is the Teen Titans Robin Tim Drake or Dick Grayson?
This is a perfectly fine question, with a perfectly fine answer. However, the question includes the incorrect assumption that the Teen Titans animated series is part of the Timm/Diniverse continuity - an assumption which is not challenged by the highest voted and accepted answers.
In such a case is it ok to go ahead and edit/remove the part of the question which gives the incorrect premise or is it better to just comment to the question with the correct info?
