Men's Rights, to a smaller degree. As an XY chromosome human, it hurts to see the pervasive biases against the XX gender. Pedophilia bias, custody battle biases, bad strains of feminism attacking the opposite sex, how accusations of abuse is viewed based on gender... May not be necessarily witch-hunt-ey, but I see so many tirades against the male demographic that are reactionary, accusative, hostile, and so forth, vitriolic. It worries me that men reading this kind of stuff might think all women think this way.
Also, conversely: anytime a hostile male demographics ridicules a single female, mob frenzy, almost like online lynching. Astonishes me that in this day and age we still have such vitriolic battles waged about sex and gender.
Oh, also: Fat Shaming. "It's okay to make fun of overweight people because it's about health." No, you're being solipsistic, preachy, small-minded, judgmental and cruel. Live and let live, I say instead. Eugenics much?
