Actually the poll doesn't even include a clear "disagree" option. It's just "Very confident," "Somewhat confident," and "Not very/Not at all confident." That last doesn't necessarily mean "I don't believe it," it could just mean "I'm not sure" or "I have no opinion." So it's very misleading to say that all of those people "don't accept" the theory.
Anyway, what's that Neil De Grasse Tyson likes to say? "The good thing about science is that it's true whether or not you believe in it."
