Sinfest Pipeline

A pipeline in which one begins with relatively progressive views except for their dislike of transgender folks, and ends with alt-right or even fascist-esque views.

Originates from the comic artist Sinfest, who began as a trans-exclusionary radical feminist, and devolved into a neo-Nazi.

Guy 2: Sounds like he went down the Sinfest Pipeline.
