Women’s bodies are treated differently than men’s bodies, in part, because men are physically and hormonally affected differently by physical appearance than women
You’re making the exact same argument as Warbler here. “Things should be treated differently because they’re different!”
I am not. Women and men are different, emotionally, physically, psychologically, sexually, et al. Therefore, women’s bodies and men’s bodies have objective reasoning for being accepted differently. There are other factors besides something as subjective as “the culture decided to be this way.”
