Donald Trump has been misogynistic in his words against women and he has said things that were indicative that he doesn't consider sexual assult to be a major problem. Most men have commited some sexual assault, and this is not okay. He needs to recognize and realize that women are his equal.
Trump's remarks about women show that he does not respect them at all. He believes that the violation of women's bodies is acceptable if you are 'a star' and in the aftermath of the video he has consistently shown that the only thing he values about women is the way they look. This attitude is not acceptable for a man in a position of authority.
Yes, the sexual phrases and non-proven claims of sexual offenses against women should make Donald Trump unfit for the Presidency because it shows that he has no respect for half of the American population. He sees women as objects and he should never be allowed to make decisions about a woman's body.
That’s why Trump’s strategy in bringing up Bill Clinton’s alleged misconduct is risky. He’s vastly lowering the bar for how much evidence is needed to make something a top-tier issue in the presidential race. It would be weird and inappropriate for Clinton to open the next debate arguing that Trump not only has a history of harassing women (for which there is a lot of evidence), but also he was probably a child molester (for which there is none).
