Typical polls suggest between 40-50% of the populace. I would suggest perhaps that you are the one who lives in ignorance of your own country as there are plenty of articles mostly suggesting that your country is home to tens of millions of science denying, fundamentalist, oddballs. Now at the same time, half the nation appears to be more rational on the issue. Vast swathes was obviously flippant, but appears to be somewhat true.
