The general realization that men and women are different and probably want different things in life. That alone causes controversy within the feminist spheres of social media.
Because it's massively overgeneralizing. As has been discussed ad nauseam elsewhere, people are influenced by the gender roles thrusted onto them from birth. Gender isn't binary, and the way a person acts doesn't always have to agree with what is "typical" of their gender.
Examples of "ugly truths" on TRP? All I've seen there is trash and misogyny.
