Hi Zest! I love that you pointed out the importance of identifying the difference between sex and gender when used in terminology!
The point you made in regards to society "rewarding" those who adhere to their gender roles is so sadly true.
Have you ever seen the TED talk The Masks We All Wear by Ashanti Branch? In it, Branch spoke of the terminology used to make him "man up" in order to meet societal expectations and how these types of phrases and judgements form a mask that everyone is expected to wear.
