Gloria Steinem is one of the founding people of modern feminism and what she says as she has observed society all these years does represent a classical view point. On the other hand, she does not have the same experience (for instance being a mother) of many main stream women and so her perspective needs to be enhanced with those of other women also
Since Gloria Steinem is the mother of classical feminism, who else would we quote to accurately represent that era? Of course, today's oh so intellectual PC types want to discount her contributions because she didn't say or do things in ways they would do them. Hilarious, considering no one would be listening to them now if she hadn't been there first.
If classical feminism is defined as liberal feminism, which is using social norms and values to integrate women into society, then quotes like, "If women are supposed to be less rational and more emotional at the beginning of our menstrual cycle when the female hormone is at its lowest level, then why isn't it logical to say that, in those few days, women behave the most like the way men behave all month long?" seem to be a little more on the radical side to me.
No, Gloria Steinem's ideology differs to some extent from classical or first wave feminism. First wave feminism focused on women's suffrage, gender equality, and had deep ties to the abolition movement. Gloria Steinem's brand of feminism was intertwined with the civil rights movement of the 60s and was deeply entrenched in women's reproductive rights, sexuality, women's place in the workplace, and family/life balance.
No, I do not think that Gloria Steinem quotes accurately represent classical feminism, because she is working towards a political cause, not towards true feminism. Steinem hides behind the power of the law to advance a political agenda. Many of her clients are not sympathetic. Many have done wrong themselves. She has political interests, not a true interest in feminism.
