Wincest is to SPN ships what Supernatural is to TV shows.
Other ships may have a greater number of fans, but no one loves their ship more deeply or with greater loyalty than Wincest fans. If love were something measurable in increments, the sheer wattage of Wincest love would eclipse all other ships in this and many other fandoms combined.
Wincest IS the greatest love story ever told. We don’t need to come out on top of fan-voted ship polls to “win.” We already win. That’s why it’s called Wincest.
