I really get a cringe when people act as if their ideals are reality when they are just ideals in their heads. Good morning: a great majority of the world lives traditional lifestyles in patriarchal societies, and even in the "best" parts the gender disparity in responsibilities and rights continues, and the stereotypes are true to some extent for most of them too.

I dislike feminism per se as I see it to be just another sexism and not a step towards gender equality, as it tends to cause sexual etichette becoming more visual and everything having gender associations, and comes with detrimental practices like positive discrimination and extension of gender equality into non gender-related parts of life.

Fighting/denying our emotions also causes us to try to rationalize perceptions driven by our emotions, by ascribing them to the world around us. Because that's a false attribution, it makes it harder for our teams to get an accurate picture of the world outside our emotions.

It's generally true.
