The source of the quote above was Andrea Dworkin. Due to a combination of her immense weight, persistent and vocal misandry, and her declaration of her sexual preference, she was often referred as "that fat, angry lesbian," - you may recognize her from that, though it's unrelated to her belief system. Her primary belief structure revolved around the concept that male sexuality was a horrific abomination, that men are the source of all evil and suffering in the world, and that men must be tamed or destroyed.
She wrote many books with dollar-and-a-half words that focused on very complex explanations for her view of human sexuality, and provided wonderful quotes like this:
"Marriage as an institution developed from rape as a practice." -- Andrea Dworkin
"The annihilation of a woman's personality, individuality, will, character, is prerequisite to male sexuality." -- Andrea Dworkin
"Only when manhood is dead - and it will perish when ravaged femininity no longer sustains it - only then will we know what it is to be free." --Andrea Dworkin
etc. She made her mark by making such outrageous statements, often. The general theme seem to be that men are evil and that female-male interaction of any type is called rape. The current trend of referring to concepts like staring or flirting as a type of rape come from this mindset.
However, she was in no way the only one. There are generations before and after her, and just as people quoted Valerie Solanas, people quote her as well. Simply search around for "radical feminist" - that's the phrase that means 'feminism but hates men' or in other words, 'female supremacist'. You'll find a ton of amusing quotes that a rational person would be hard pressed to believe.
The general consensus is that she probably did far more harm to the cause of female equality than she did to help it. However, many people today don't understand why that is, and parrot her quotes and ideas without awareness.
