Choosing by Gender, how is this wrong?

I do not understand the hatred by many towards Hillary Clinton. I can understand some not wanting to vote for her who disagree with particular issues, but not the hatred. It seems too personal and I just don't get where that level of hatred comes from.

I think some must come from the barrage of conservative negativity info, opinions spewed continually towards women in general that has seeped in the MSM watchers mentality, by so many talking heads (particularly on Faux News) with the increase of exploitive portrayal of the 'perfect woman eye-candy'; and the increase of the bible-thumping fundamentalist influence and reinforcement of a woman's role according to the men who wrote the bible.

And according to the following article the term of Feminist with younger people appears to be a negative thing. When did this happen?

Feminists are better matesSupporters of equality for women also have stronger relationships, new research says

Laurie Rudman of Rutgers University had found in earlier research that negative stereotypes of feminists--that they're unattractive, man-hating lesbians, in a nutshell--cause young adults to distance themselves from the "F-word" and tone down their demands for equality. A majority of college-age respondents agreed with such statements as "Most men would probably not want to date a feminist" and "Romance depends, in part, on men being allowed to be in charge."
This was alarming to Rudman, who is old enough to remember the heyday of the women's rights movement in the 1970s. Continued efforts to achieve gender equality could be seriously hurt, she reasoned, if women (and men) think it comes at the expense of love.

When ever did a woman want to be less than a man? I never saw that as my female peers, at the very least, always considered us equal to, although we saw it was and is still a man's world on too many levels and issues. But admiration of a strong woman was greeted with awe because it still seems so rare.

Unfortunately, I haven't had the pleasure of having a feminist man in the flesh for my personal enjoyment. I have seen them from afar-Bill Clinton comes to mind as does many good Democrat men in the Congress.

"If you're a woman paired with a male feminist," said Rudman, "you have a healthier relationship across the board"--better in terms of relationship quality, equality, stability and sexual satisfaction.

"And men paired with female feminists have greater sexual satisfaction and greater relationship stability," she said. "So, [there were] higher scores on two of the four dimensions, with no difference on the other two."

"If a relationship is based on authoritarian control, keeping one person on top and the other underneath, it gets old pretty fast--for both partners, really," said Ogden, a Boston sex therapist who surveyed 3,810 people for her book "The Heart and Soul of Sex."

"In an egalitarian relationship, there is more flow of give and take," she said, "and that's the romantic tension. That tension--the sexual desire--is in that space between you where you're able to flow back and forth."

I can clearly see that if one is a Feminist, one is more aware, more open-minded and healthier as a human being.

So many people like to jump on the gender card as a bad reason to make a choice for anything, let alone for a presidential choice.
Well, what do you think the main motivation of the men in charge wanting to maintain control of all things big and powerful? Besides money the obvious is the big boys club where still very few women dare to tread.
It seems that men use and play the gender card All The Time.
