If the bible really was controlled oppositon than they wouldn't need to have special versions of it like Christian Zionism, it's also anti-globalism. The biggest problem /pol/ has with Christianity is that it's not race based, as loving said race neighbor. Because of the atheist notion that "God can't be proven with science than it must not be true" idea, /pol/ takes the same stance on Christianity, except even more jaded because it's seen as automatically Judaism despite the obvious.
Sometimes people are so specialized in an ideology that they don't take the time to have comprehension in what they're dismission. It's the same with /fringe/ posters they're so automatically opposing that it's simply an inversion of the other side and if states an opposing view they're automatically wrong by default. asked /fringe/ about the people who said that yoga is demonic and used prayer to Christ to stop the demonic oppression, and the respounce i got was " poeple lie". Another example was a poster on here who was trying to make the point that Kundalini Yoga wasn't demonic because it didn't specifically say in the bible. He said that self-Godhood wasn't satanic because it was in the bible, and said that the snake in Adam and eve wasn't lying. Even though the symptoms for Kundalini were blatantly demonic (including involuntary and unknown yoga positions) the poster kept simply dismissing all claims that it was.
It's important to look at the critics of Christianity and see if there are answers to this, or else we would be stuck with a false god because we grew up in an environment that worshiped the wrong denomination. You also need to know where these criticisms are coming from, the idea of Christianity being "slave morality" comes Nietzsche.
It's better to investigate yourself than to debate criticism, investigating these things should separate the Jehovah witnesses and Mormons from the genuine/authentic Christians. When /fringe/ made a big impact on /pol/, every one was regurgitating the "yhwh is saturn/satan" meme over and over, even though the idolizing cross isn't biblical, and directly tells you to watch out for God symbolism. People will never get over the blind christian stereotype, debates don't help find the truth.
