I didn't look at much of them because, first of all, Bryan Denlinger teaches crazy things like that you need to marry someone of the same skin color or you sin against God. So... it's the pot calling the kettle black. The main reason he hates Steven Anderson is because Denlinger is strictly Pre-Trib, to the point that he suspects anyone who doesn't believe the false Pre-Trib doctrine isn't of Christ.
Second, I saw one part where Anderson said that Judaism is a Satanic and wicked religion. Actually, I wouldn't disagree with that. The Torah and the law of God and the prophets are all good and holy, but Judaism is a separate religion. Judaism, as far I know, is never mentioned in Scripture, and there are all sorts of traditions that are followed in Judaism that are not part of God's commandment, including things like the Kabbalah, which is Jewish/Babylonian mysticism. So whereas Denlinger might point out some things that are true, especially when it comes to Anderson's scoffing, I am not sure that Denlinger himself is a Christian; Denlinger has a lot bigger problems he needs to address before he starts exposing anyone.
If Steven Anderson believes the Holocaust never happened; I don't really care. That's why I'm addressing his foundational doctrines, especially concerning Salvation, first and foremost. The rest of that stuff is mostly irrelevant, and in many cases, it's false converts bickering among themselves who is "holier" than the other, when they all need repentance.
