You keep going back to wikipedia to say we’re all wrong about how Mary Sue is a derogatory term used towards female characters, yet you seem to have ignored this one paragrpah in that same wiki entry
Wikipedia isn’t the source. I’ve only posted two excerpts from Wikipedia, both of which are sourced from other places, primarily this site:
http://fmwriters.com/Visionback/Issue30/marysue.htm
“Christine Scodari, a researcher in media studies from gender perspective, noticed a tendency within slash fandom to label major female characters (e.g. Nyota Uhura in the Star Trek 2009 film reboot) as “Mary Sues” because the slash fans “begrudged” how the development of the female character takes away screen time from slashable male characters.[16]”
Only correct application of the term is relevant. Every word/term in the English language has been misapplied by someone, somewhere, countless times.
Like i said before, just because a word or term originated with a certain meaning does not mean that , after time, it can’t become something that becomes commonly used as a derogatory term towards a race or sex. It is more widely used as in derogatory form towards female characters that it is used in its original meaning. You only have to go on certain forums and sites to see just how many use it because they hate the “female agenda” in Hollywood as they see it. The comments section on youtube alone since TFA came out was littered with the comments using “Mary Sue” in a derogatory fashion.
The reasons given for Rey being a Mary Sue have nothing to do with her sex. And whether or not a “female agenda” resulted in the creation of a Mary Sue is a completely different argument. Rey is a Mary Sue regardless of what led to her creation. If your theory were true, people would commonly be calling all female leads in major works of fiction “Mary Sues”, yet that hasn’t happened. Additionally, there wouldn’t be any male Mary Sues, but in reality, the most famous one until Rey came along was Wesley Crusher.
