Even though the exact number may be wrong, the point still stands.

What exact number, and what point? No point based on the assertion that “Mary Sue” is a “misogynistic” term can stand, because it is at odds with the widely accepted definition of the term, which you can read about on Wikipedia, TV Tropes, and various other places.

I’m gonna go with “no” on this one. It’s very hard to make the argument that a term using very clearly feminine names with a male-named counterpart is not gender specific.

It is not sex-specific. Once again:

A Mary Sue is an idealized and seemingly perfect fictional character. Often, this character is recognized as an author insert or wish fulfillment.[1] They can usually perform better at tasks than should be possible given the amount of training or experience. Sometimes, the name is reserved only for women, but more often the name is used for both sexes. A male can also be referred to as a Gary Stu, but more commonly either sex is called a Mary Sue. [2][3]

Note the parts I placed in bold.

The name of the trope, “Mary Sue”, was taken from the name of a character used in a parody that was written specifically to demonstrate this type of character.

This is your tacit admission that you haven’t even bothered to do your homework in order to avoid commenting on things you know nothing about:

The term “Mary Sue” comes from the name of a character created by Paula Smith in 1973 for her parody story “A Trekkie’s Tale”[4]:15 published in her fanzine Menagerie #2.[5]
