You don’t have the ability to determine bias in a straight poll, yet if you exclude 9 of 10 on the sample you’ve created a bias because they are not representative.
That’s again not how sampling bias works. If you called these people and asked what their favorite color was, you wouldn’t have an unrepresentative sample. It’s only if your sample is itself biased toward a response. Very small samples might have larger error bars, but they aren’t inherently unrepresentative unless the method of sampling is corelated with a response.

F your sample is not representative then the poll is invalid. Perhaps you know better
