Quillette is a right-wing online magazine that tries to present itself as alt-center when in reality it serves to legitimize many views shared by the alt-right. For example, it regularly publishes articles that are anti-feminist and anti-transgender, with some articles more controversially supporting racialism/HBD pseudoscience. It has published an article defending Noah Carl, a pseudoscientist who writes Islamophobic papers in the OpenPsych pseudojournals.[2]
In the media, Quillette is often described as "intellectual dark web".[3].
