It’s actually the right that has a problem defining “female.” A person born with female genitalia is 100% female, unless of course she’s an Algerian boxer; then it’s “complicated.”
At the risk of sounding horribly pedantic, cow farts aren’t the problem. Though it’s not nearly as funny, belches are the main source of methane from Ol’ Bessie. The way they digest food, most methane is produced early on in their stomachs, not later on in their intestinal tracts. And their total contribution (no matter which end it comes out of) is about 3-4% of AGW.
