"What's your evidence" or "where from did you get this information" are completely different questions from "Who told you this".

The target question did presuppose that the poster did not come to the opinion by studying different sources, by comparing different accounts, or perhaps even by personal experience, however questionable personal experience might be. It implied that the poster came to this opinion simply by being told. The poster is seen in this formulation as a passive recipient of information unable to think critically.

I grant, dianavan, that the question may have been formulated without these implications in mind, but when SJ called it a low shot it might have been an indication that the question can be read differently from how it was intended.

My only intention in my post was to point out that calling this question 'simple' was wrong.
