I have no doubt that many of the Art and Feminism articles that are nominated for deletion are nominated due to gender bias (as some of them seem rather trivial to find sources for and improve), but many of them are also legitimately on the notability borderline. At all of the Art and Feminism editathons that I've volunteered at, I've discouraged people from creating articles about people they knew personally, and encouraged them to use the lists at https://en.wikipedia.org/wiki/Wikipedia:Meetup/ArtAndFeminism/Tasks instead. If you are helping to run an Art and Feminism editathon, I would also suggest doing this, as it provides more value for Wikipedia and leads to fewer deletions. I would also like to encourage everyone to edit the lists at https://en.wikipedia.org/wiki/Wikipedia:Meetup/ArtAndFeminism/Tasks and help keep them full of good suggestions. Editathons are a great tool for addressing the gendergap, and I would hate for them to get a reputation for just being self-promotional events.
