As Gawker noted in 2011,
Jesus Ween is not, in fact, a celebration of Jesus's ween, but rather "a non for Profit Organisation [sic] also known as JesusWin…focused on helping people live a better life."Those participating in JesusWeen hand out Christian bibles instead of candy (or at least candy with bible verses printed on the wrappers). They do not allow their children to wear costumes. You know, because that would be evil.
If it is fun or feels good in some way, you can bet that fundamentalist Christians somewhere are trying to figure out how to stop people from doing it. Not only is Halloween fun, but many fundamentalist Christians have decided that it is genuinely evil. That means that those who participate in it are evil. You don't want to be evil, do you?
JesusWeen may be a relatively new phenomenon (it appears to have been born in 2011), but the sentiment underlying it is anything but new. I remember the fundamentalist Christian families not allowing their children to participate in Halloween as far back as grade school. They were a tiny minority back then where I was growing up on the West Coast. They are not so tiny here in Mississippi today. I am not even sure that they are a minority.
