Even with the best of intentions, 310 people interviewed is just not enough to be able to draw conclusions about the way the society they live in thinks and feels.
It makes more sense looking at the whole of that society, instead.
If we look at the voting for the recent Presidential election, women gained 61 million votes, men 64.4 million. Does this show a resistance to voting for women? I hardly think so, any more than the previous two elections showed a resistance for voting for a black person.
