I believe radical feminism is actually one branch of a modern, radical leftist pseudo-religious, political movement whose true goal is to establish a radical left authoritarian government to enforce it's "morals" on everyone else.
The beliefs or "doctrines" of this pseudo-religion are as follows:
Hatred of Men - Men are violent, savage and sexually perverted by nature. Men need to be neutered and taught feminine "virtues" in order to be considered civilized human beings. Men have used violence (physical and otherwise) to hold women back for thousands of years and this needs to change.
Love/Worship of Women - Women are kind, gentle, nurturing, strong, intelligent and otherwise superior to men in almost every way that matters. Everyone should be more like women and women should be treated as "better" than men in almost every way. Only the brutish physical violence of men has held women back because, of course, women are too "civilized" to use the same tactics on men.
Hatred of America - America is inherently evil, racist, sexist, bigoted, unfair, unjust and needs to be cut down to size and denigrated until it has been put in it's place.
Love/Worship of [Leftist, Authoritarian] Government - Government under their control would be transparent, benevolent, caring, nurturing, fair, just, tolerant and all of the things that America isn't. If only that old, outdated Constitution and political opponents would get out of the way. This is perhaps the single most important "doctrine" of this religion, as achieving said government means the fulfillment of all "doctrines" listed here.
Hatred of Whites/Caucasians - White people are the scourge of this earth and the primary cause of most evil throughout history. They need to be cut down to size and denigrated until they've been put in their place. In contrast, minorities of all kinds should be revered and respected merely because they aren't white.
Hatred of Religion (especially Christianity since it's so common in America) - Religion is "opium" for the masses, a relic of a bygone era and merely used as a "tool" for controlling people. Religious people are intolerant, ignorant, idiots; dangerous to themselves and others. The only good religion is religion that is merely therapeutic or religion that advocates the "doctrines" listed here.
Love/Worship of Nature - Human beings are the greatest evil on this planet and nature/animals are to be revered, worshiped and imitated in many cases (i.e. appeal to nature fallacy).
General Belief in Sensual Morality (i.e. Pleasure = Morally Good, Pain = Morally Bad) - Anything that causes physical or emotional pleasure is good and should be encouraged as long as it doesn't cause pain. Anything that causes physical or emotional pain is wrong and should be discouraged or punished.
Intolerance as the Greatest Sin - Intolerance is the great sin. Anyone who is "intolerant" deserves "intolerance" themselves. Verbal abuse, bullying and censorship are perfectly acceptable towards people who are "intolerant". Anyone who disagrees with the "doctrines" listed here are, by definition, "intolerant" and open to said abuse.
Belief in a Utopian Future - Human beings will continue to evolve biologically, culturally, socially, politically, technologically and every other way until all obstacles plaguing the human race have been solved (disease, war, violence, criminal behavior, greed, etc.), the doctrines of this belief system have been fulfilled and human beings expand to the stars in the glorious and beautiful future.
That's my current working theory, anyways.
