As part of its campaign to give women the same rights men have to bare chests in public, the Go Topless organization is linking to a YouTube video that explains why men have nipples.

Says Go Topless on its Facebook page: “We all started as female, and that’s why men have nipples. It makes absolutely no sense to censor female nipples in public.”

GoTopless Day 2015 is set for Aug. 23.
