Really? When Gallup puts out a poll question is the first step for the respondent to question the intent and meaning of the poll query by asking Gallup to clarify, explain and justify? No. If one does not like the words of the poll, then do not participate.
No, the first step before asking the question is to ensure that the meaning of the question is obvious. Then you ask the question.
If somebody asked me: who do you believe should be the next president of the USA: A or B, and I did not agree with either (or any) candidate then I would refuse to answer the question (though sometimes they give a third option: C None of the above). The question is clear though. I don't need to ask: what do you mean by president? Where is the USA? etc...
This "I have faith that the sutras were taught by Buddha in some manner or form." is just WAY too vague for a number of reasons:
1. taught by Buddha. The Buddha or a Buddha?
2. the sutras. Suttas too? Tantras? All the Sutra? What about Canonical texts (Sutra and Sutta) that have a known author/teacher other than the historical Buddha? You mean like the whole Canon?
I answered "No" and gave the example of the Platform Sutra. If I knew Sutta were included I would give the example of a number of Sutta taught by Sariputa, etc... Sutra taught by Bodhisattvas. Tantras taught by Sambogakaya Buddhas.
The question is unclear, so that makes the results irrelevant.
Now if you started the poll just to get people discussing, fair enough. This still makes the results of the poll itself invalid.
