Btw, I am 99 percent sure the switch of terms was not only artificial, but also pre-planned.
How? Because when the concept of social role based on characteristic was introduced, they called it a "gender ROLE". That phrase is an amalgamation of definitions. If gender = sex, then sex role is exactly, what would fit the lefite definition of "gender". And the lefties used to use the phrase.
It as if they were using the phrase "knife cutter" while meaning only "knife". It is not a phrase, that had any other reason to exist, then bridge the definition slowly.
