Sinfest

Sinfest is a long-running daily American comic strip by Tatsuya Ishida. It originally appeared in the Daily Bruin student newspaper between 1991 and 1994. Ishida relaunched the comic strip in 2000 by self-publishing it online as a webcomic. Sinfest has also been collected into five printed books; Dark Horse Comics published two of them, in 2009 and 2011.

The comic has received mixed reactions over the years due to its treatment of topics such as race, feminism, politics, and sexism. Its themes and tone have shifted significantly over time, with the 1990s incarnation often regarded as particularly crass. During the 2000s, the comic adopted a black comedy style, frequently referencing pop culture. In 2008, it began incorporating more overt political and ideological themes, including elements of radical feminism from 2011 onward. In 2022, the comic's content led to the author's bans from platforms such as Patreon and Twitter for violating policies on hateful content.
