Alright, so, there are a few blatant hypocrisies present in this:
#1: Oprah endorsing political figures.
So do most Christian churches in the U.S., and that's in spite of something called "separation of Church and State".
#2: Oprah leading astray.
As far as I'm concerned, you all have nothing to support your arguments, so you can't claim that you aren't "leading astray" all the people who buy into your message.
#3: "Church of Oprah".
Please, that's as ridiculous as referring to the Christian church as a "cult". Actually, more so, as by all means most Christian churches are akin to cults by definition of their practices. A church requires veneration of both a religious theory and a figurehead. Not only do Oprah's beliefs fail to constitute a religious ideology (they don't concern the origins of the universe, merely our individual purposes within it), but Oprah does not establish herself as divine or worthy of worship.
I totally appreciate that this was obviously put together by a fundamentalist/authoritative Christian, and if you want to embrace this view of Oprah Winfrey, be my guest. I, personally, see nothing wrong with her: she doesn't demand tithes or tributes, she doesn't threaten people using relative beliefs about Heaven and Hell/eternal torture, and she embraces different beliefs than her own.
