So, I posted an answer for this question, and it was just deleted:
In response to a question about what the theologians of the Early Church thought about Rabbinical Judaism, I posted an answer explaining the context of the time, the three main branches of the ancient Hebrew religion at that time period (the Sadducees, the Pharisees, and the Christians), how the Sadducees died out following the destruction of the Temple, and how the Pharisees came to become modern-day Jews.
I then quoted one of Jesus's speeches from the Bible, where he condemned the Pharisees as the children of Satan.
Given that Jesus was definitely the most important theologian of the early Christian Church (you know, since his teachings formed the basis of it), I was very surprised to see this answer downvoted and then deleted. This seems bizarre to me; Jesus's skill as a theologian is very clearly shown in the Bible, and it was by his instructions that the early Church was even created to begin with, so an answer quoting him should definitely be a valid answer to the question.
Why was my answer deleted? I could sort of see a reason for it if people claimed that it was anti-Semitic (though I tried to avoid that by simply presenting factual information - I'd even posted a link to the Encyclopedia Britannica minutes before my post was deleted to support the "Pharisees became modern Jews" assertion); however, that doesn't seem to be the reason for it, since nobody mentioned that in the answer's comments, and I don't seem to have gotten the -100 Reputation hit that you get from getting a post deleted for being "hateful or abusive".
