Rodger is frequently cited as an influence by incels involved in or suspected of other mass killings, often referring to their attacks as "going E.R."[19][20][21][22][23][24] The media and academia have since described Rodger as the author of the modern incel ideology.[25]
This is either a lie or a half-truth. The term "go ER" is nothing more than a meme on forums, and no one really takes it seriously, and those who use it don't become mass shooters. The people who actually become mass shooters have mental problems and have little to nothing to do with the community.
