"Racism against white people does not exist in the US, Canada, most of Europe, etc. because white people are not a racial minority."
That's a flat-out lie.
Racism goes beyond being a minority; it's an extension of hatred for someone's skin color, regardless of whether they're the minority or not, because it's an advanced form of prejudice.
One in which unfair, often VIOLENT, treatment is acceptable simply due to being the odd one out.
There are videos out there, RIGHT NOW ON YOUTUBE, of INNOCENT WHITE PEOPLE being BEATEN SENSELESS for merely WALKING DOWN THE STREET in a neighborhood where black people are the majority.
In that situation, you can't say that they aren't a minority, so even by your narrow definition of racism, there are plenty of situations where racism applies.
Similarly, misandry DOES exist, as an advanced form of SEXISM against men.
A group of Anita's buddies, for example, attended a college function where it was suggested that men not be given the right to speak before women in a classroom, despite the fact that, as things stand now, the majority of teachers in colleges do not discriminate between genders when deciding on who they call upon during class.
There's an entire video on this; it's Misandry in action, and only someone blind to Anita's faults as a radical would ever deny that what they are proposing is WRONG, and is NOT what proper Feminism is striving to achieve.
Modern feminism has turned into an attempt by misandrists to bring men to heel, and to give women all of the benefits of chivalry and "equality" with NONE of the responsibilities or accountability that comes with being equal to their counterparts.
In their ideal world, a man saying "hi" without permission is something that they would not allow [I'm not even kidding; there is at least one feminist out there RIGHT NOW, who believes men should need CONSENT to greet a woman. https://www.youtube.com/watch?v=21NWphbQm18], let alone talking before women in classrooms, hitting women even in self-defense, and being given the chance to protest against false criminal accusations instead of being sent directly to jail.
It's not a "theory", it's something for which we have PLENTY OF REAL-WORLD EVIDENCE.
Misandry exists just as surely as Misogyny does, because in modern-day America, at least, there isn't a patriarchy anymore.
Men don't "rule" over women in modern-day America.[unless you're living in some sort of screwed-up area with no concept of modern societal law and equality]
Walk out onto the street and order a woman to do something, and you're going to get denied or ignored at best, slapped and beaten as you deserve to be for trying something so misogynistic at worst, unlike in the pre-modern days where not listening to a man could, in many parts of the world, get a woman KILLED.
Her opinions are inherently nonsensical; THAT'S why we're disagreeing with them.
Anita is a MISANDRIST. You can't honestly deny that without lying about all the harm she has done to the cause of ACTUAL FEMINISTS who sincerely want equality with men, rather than a lop-sided world where women get all the benefits of chivalry, with none of the accountability that men have to put up with for their actions.
