Does anyone really claim that though?
KJK's statement seems extremely hyperbolic to me, but I don't think I'd interpret her, or most other people I hear say they'll vote for Trump, as saying they like or approve of him personally. Or that he is a friend to women.
It's a statement about who they think will be the best political outcome, of the available choices. (Or sometimes, least worse outcome.) That doesn't always mean the nicest person, or even morally most upright person. People can be real knobs or morally questionable, but effective leaders, or lead an effective team, or be somewhat less shit than the other option.
People here making this argument get very tied up on Trump will screw over abortion rights, and Harris will somehow preserve or even improve them. I don't think it's likely to make a difference one way or another, it's been kicked to the states and neither Harris nor Trump will be able to influence much. (I doubt Trump wants to, I don't think he cares much personally and it would lose him more than he would gain politically.) So it's an irrelevancy in practical terms.
I do think that Trump or Harris could make a big difference on gender questions and both are likely to try and do so. Harris because she is a True Believer and so are her base supporters, and Trump because it would be easy, sit well with his constituency, and would be good for his ego fulfillment. He also likely believes that it reflects the truth but I doubt that motivates him significantly.
