A non straw man of your first argument would be the definition of “rape.” Most people believe forced sex should be illegal.
But rape also means consent, in America, so you get “statutory” rape, and Romeo and Juliet laws, and different handling of intoxication all over the world. If two people are black out drunk, can either rape the other if they ostensibly agreed while intoxicated? Does it matter the sex of the participants?
Look no further than any Reddit post and you will see that at least some people think a 17 year old male having sex with a 25 year old female teacher should not be considered rape.
The definition of rape is unequivocally political.
