Is there really such a thing as a gender binary? I'm not convinced. What makes a person male or female?
In biological terms
Male is someone born with a penis
Female is someone born with a vigina
Our genders are based on our reproductive organs. I think its ridiclous that people pretend gender is a social construct and there aren't clear difference between biological males and females
Science does show clear biological differences between general* male and female thinking in some rather minute areas (such as sensory things and such). It stretches credulity to claim biological male and biological female are not things at all. This is not to say that some kind of binary doesn't exist in some respects, just that male and female is clearly part of the basic framework and it's very ascientific to claim otherwise.
*=word choice here intentionally allows for deviation from the norm/average/whatever isn't statistically is the likeliest
