Try to delete all the female only ones.

Be bold: Delete them *all* and let the data gods sort them out. I think discussion in the early days of this list pretty much established from the get-go that Wikipe-tan was a major turnoff, that she conjured up some pretty unsavory stereotypes (of both female and male Wikipedians, I should add), that she was unrepresentative and that Jimbo was not a fan.
A few years ago we got rid of Bad Jokes and Other Deleted Nonsense. I loved those pages; I had added quite a bit to them. But I could see the point of the deletion nom. It created licensing problems and violated WP:DENY. We moved it to Uncyclopedia (or did we?). Wikipedia survived, and grew up just a little more. We could certainly survive giving Wikipe-tan her walking papers.
