Q1: What is the subject of this article?
A1: This article is about a particular misogynistic online subculture of people who self-identify as "involuntary celibates" or "incels" based on their inability to find a romantic or sexual partner. It is not about all people who are unable to find a romantic or sexual partner or all people to whom the phrase "involuntary celibate" could be applied, but only to that subculture.
Q2: Why is this article only about the subculture/community of self-identified "incels", and not about the idea of involuntary celibacy more broadly?
A2: It is the subculture which has achieved notability independent of concepts Wikipedia already covers, such as sexual frustration, celibacy, and sexual abstinence. Although a separate article about the broader concept of involuntary celibacy could be created, such articles have been deleted in the past in favor of coverage in existing articles.
Q3: Why is this article so negative?
A3: Articles on Wikipedia reflect the way subjects are covered in reliable, published sources with a reputation for fact-checking and accuracy. The articles cover aspects of those subjects in accordance with the extent to which those aspects are covered in reliable sources. There are negative elements of the subject in this article because that is the way many of the reliable sources cover it. If coverage of the subject changes, the article should be updated to reflect that.
