IMPORTANT! HOW TO DEFEAT LEFTIES!

The only way to defeat lefties is to get them to argue your point.
The main way to do this is by going more extreme than them in your dialogue.
Example:
Leftie: Men make more than women and we have to end the gender wage gap!
Your response: Your argument is invalid. There is no gender! Prove me wrong!

Lefties argues: of course there’s gender.... then they go on and on about what makes men men and what makes women women.

Your response: (This is where you get ridiculous) (because of transgender folks that the left wants us to accept so badly, just play devils advocate with them and keep a transgender person in mind when describing men and women until they get frustrated).
.... response... men can get pregnant too and they are subject to harsher vacation time rules compared with women who get pregnant.
See, MEN are underserved!

Leftie: no, they’re transgendered! Screech!

You response: stop that! My friend who is male doesn’t like to be called transgender as that’s a condescending term. They are male. Always have been and always will be. (Keep in mind you are talking about your maybe fictitious friend who was born with a female body)

By this time you get the point. Argue them into a circle by taking the more extreme position to point out the flaws in their logic if followed to the extreme. They will end up making points for you that defeat their own arguments!
