I'm confused by this response (not the OP). Do you think that they were saying Clinton's being a woman would make her a worse president?
I took it to mean that there are a decent-sized group of Americans who do believe that (probably not including the OP), and as a result nothing she could have done would have won her those votes.
I don't know how many people voted against Clinton because she's a woman, but I guarantee you it's not 0. As a result, it needs to be talked about. While it'd be a better world if people didn't focus on such irrelevancies, the fact that some do means we can't act like it's non-existant.
