The only time the subject of "gender" came up was when I was studying German in high school and college, and later Russian in college. Both languages have three genders, masculine, feminine and neuter, which determine the endings of nouns, adjectives and other parts of speech.
Exactly! People should quit letting the demo-commie nut-jobs set the terms of the debate. Don’t accept their premise that referring to biological sex can be referred to as ‘gender’. Point them out as an uneducated neanderthal who can’t grasp the concept of biological sex. Laugh at them and refuse to play the game on their terms.
