Inseminary: Sex is Not Like Race

Three quick clarifications to my position:
1. sex is not like race or class because, unlike race and class, sex is not a social construct but a very clearly defined natural category that precedes ALL human society.
2. Men don't get to then keep male evolved genetics. We aren't independent lineages, even though we look different. Men and women have the SAME genetics other than A SINGLE gene.
3. Competition is imposed, not opted for by individual males.
