“Misandry”—literally, the hatred of men—is an accusation that’s been flung at feminists since the dawn of the women’s movement: By empowering women, critics argue, feminists are really oppressing men. Now, feminists are ironically embracing the man-hating label: The ironic misandrist sips from a mug marked “MALE TEARS,” frosts her cakes with the phrase “KILL ALL MEN,” and affixes “MISANDRY” heart pins to her lapel. Ironic misandry is “a reductio ad absurdum,” explains Jess Zimmerman, an editor at Medium and the proud owner of a “MALE TEARS” mug. (“I drink them to increase my strength,” she notes.) “It's inhabiting the most exaggerated, implausible distortion of your position, in order to show that it's ridiculous.”
OK, here goes.
"Racism" - literally, hatred and discrimination against people based on their race - is an accusation that's been flung at white supremacists since the dawn of the movement. By empowering white people, critics argue, white supremacists are really oppressing blacks. Now, white supremacists are ironically embracing the black-hating label: The ironic racist sips from a mug marked "NIGGER'S TEARS", frosts her cake with the phrase "KILL ALL BLACKS" and affixes "RACISM" heart pins to her lapel. Ironic racism is a "reductio ad absurdum", explains Jess Zimmerman, an editor and the proud owner of a "NIGGER'S TEARS" mug. " (“I drink them to increase my strength,” she notes.) “It's inhabiting the most exaggerated, implausible distortion of your position, in order to show that it's ridiculous.”
Now that, my friends, is a reductio ad absurdum. A real one.

"Ironic misandry" is not a reductio. What it actually is is an attempt to cover up the existence of real misandry by exaggerating that misandry, then pointing to the exaggerated version and saying "see, its ridiculous, there's no such thing as misandry."
