Her personality is not likeable to many people
Hillary may be simply unlikeable to many— not to all people, but enough people didn’t like her to the extent that they did not vote for her when they should have. Because, well, Trump.
Of course there were other reasons than likeability not to vote for Hillary. They matter. They will have swayed others who may have liked Hillary Clinton and still did not vote for her. But the people who did not like her or even felt a dislike were crucial to her losing the election.
You can make connections between liking her or not and other presumptions about people. But doing so is wrong, it’s bad psychology and it’s paternalistic. Complaining about it is understandable, but not everyone is doing this. If you don’t like Hillary Clinton, you can still have respect for her.
Not liking Hillary Clinton is, in some circles, exactly the same as liking her is in other circles. It gets you ostracized, because some groups of people are overly politicized and polarized. “If you have half a brain” (…Pina colada…) you realize that the sensible position is to not ostracize people for the politicians they like, unless they are murderers (which Clinton gets accused of, weirdly) and vile rapists.
Not everyone who thinks you are incorrect to like Mrs. Clinton believes you are an idiot because of it. Certainly not everyone who does not understand why you like her believes that. They may simply not agree. While Melissa McEwan may be right about some of the polarized political penguins, she is generalizing to the point where she seems to be seeking the role of victim. I hope I’m reading too much into her complaint. That is because I generally like people who like Hillary, even though I don’t. Given the chance, I still would have voted for her. It’s not all black and white, it’s grey. In fact, like Mrs. Clinton, it’s very grey.
