I'd be willing to bet a month's worth of my income that a majority of the population doesn't view it this way. The only people I know who view things this way are very far to the right (and this group is not the majority on the far right by any means).
The only part I'd be willing to bet is shared by more than 50% of the population is that all men are created equal (in theory at least; there are plenty of people with disabilities who would disagree that they are viewed as equals in practice; you needn't think too far beyond who would be sacrificed on a deserted island first and without much conflict).
