OK, I’ll try to explain the joke to the best if my ability…
You know how SJWs like to use words like “cis-gendered” (meaning not changing you biological sex or gender identity) and “hetero-normative intercourse?” (Straight sex.) As far as I know” every single human being is created by the act of a sperm penetrating an egg, and as we all know, sperm comes from men and eggs from women. The most common way for sperm to mix with eggs is for men to fuck women. Since men apparently benefit from sex more than women (feel free to correct me if I’m wrong,) it can be construed as “reaffirming the patriarchy.”
So basically, two straight people, who’s never had a sex-change operation (cis-gendered), having straight sex (hetero-normative intercourse) makes men happy (reaffirms the patriarchy.) Or so it would seem.
BTW, I’m not an SJW and I fucking detest political correctness. If I ever talk politically correct, I always do so ironically.
