Generally feminists don't like heroes, because a hero is a big, strong, masculine, courageous, male warrior. Like Hercules or Achilles, or Perseus, or Conan the Barbarian.
And most feminists really seem to hate strong, powerful, masculine men. (Especially the radical feminists, who want to make all men more like women, and make all women more like men. That is, they want to erase all the natural and wonderful differences between the sexes. How boring.)
Perhaps you're asking about feminist *heroines*?
That is, are there women that some feminists regard as admirable? I'm sure there are.
Most of them I would not agree with, except maybe Margaret Sanger, the founder of Planned Parenthood.
When I was younger, one of my heroines was the novelist and philosopher Ayn Rand, because she wrote some very strong heroines into her novels, women who were engineers and executives, etc. That was quite unusual fifty years ago. But mainly Rand was a very passionate woman, who loved men and wanted more than anything else to have a heroic man to look up to. Her male heroes were regarded as gods by the women who adored them, one scene described how Kira felt like a priestess worshipping her man as if he were a god. Very romantic.
She also felt that was the very essence of femininity. In fact, there is some famous quote where she defines hero-worship as the essence of femininity. She was also very fond of dominant men, and her books became scandalously famous for, among other more notable features, her sex scenes. In Atlas Shrugged the heroine is raped by the hero, and she is thrilled and delighted, and deeply in love with him. Many feminists later got offended by Ayn Rand, for her apparent glorification of rape. But she explained it as "rape by engraved invitation."
A few years back, there was a book with various feminists giving their interpretations of Ayn Rand's work. It was pretty ironic, because she did not consider herself a feminist at all. And neither am I. But that's one of the very few things I still have in common with Ayn Rand these days.
I outgrew my youthful feminist idealism years ago, when I realized how ridiculous "mainstream" feminism was becoming. And now it's even worse, it has become downright man-hating nonsense that is destructive to men and women alike. But the good news is that when anything becomes that absurd, then inevitably the pendulum will start to swing back in the other direction, there will be a growing backlash against the radical extremes. And the backlash against feminism is well underway, and getting bigger every year.
