"In Britain, where atheism dominates, people dislike underdogs and tend to root for the contestant who is favored to win."
Doesn't the Church of England dominate in Britain?
Oh, wait. I forgot. They're not true Christians, thus they're a bunch of heathen atheists.
"The opposite is true in the Christian United States, where the underdogs have traditionally been the favorites of the people."
That stems from the country's origins and has fuck all to do with religion.
"However, as the liberal media in the United States becomes increasingly atheistic, victories by underdogs are increasingly met with dismay or disapproval."
The media is not "liberal." At best it's impartial but damn near all of it skews to the right to some degree.
"Why do atheists dislike underdogs?"
See my other post Andy and take my advice: get some help; you're not well.
"One obvious reason is that atheism is about control."
Obviously. This is why we have weekly indoctrination sessions and are told constantly that we're worthless people deserving of the most atrocious punishments for minor infractions of bizarre rules. But don't worry, the god we don't believe in loves us just the same and wants to "save" us from said punishments.
"Stalin, a famous atheist in the 20th century, probably did not like underdogs."
Probably? I thought you were supposed to be running a legitimate encyclopedia Andy. "Probably" doesn't belong in a legitimate encyclopedia article. If it's not a fact that can be proved, don't mention it.
"Underdogs threaten the status quo and the worldview of atheists. Upset victories are unsettling to people like Stalin."
Stalin is long dead you idiot.
