I don't think this is a fair poll. It's not black and white. Someone could believe there is evidence which supports the idea that earth is not a sphere, oblate spheroid, or spheroid and not be utterly convinced of that.
A better poll would be this
1. I think the evidence overwhelmingly supports the idea that earth is not a sphere, oblate spheroid, or spheroid.
2. I think the evidence slightly supports the idea that earth is not a sphere, oblate spheroid, or spheroid.
3. I think the evidence neither supports or rejects the idea that earth is not a sphere, oblate spheroid, or spheroid.
4. I think the evidence slightly rejects the idea that earth is not a sphere, oblate spheroid, or spheroid.
5. I think the evidence slightly overwhelmingly rejects the idea that earth is not a sphere, oblate spheroid, or spheroid.
