I don't trust verbal research. Nothing personal, but "verbal research" is unverifiable. I can't go to the library and pick up "verbal research."
At the same time, the fact that you were unable to look up what Preterism and Amillenialism means that you cannot be an expert on the topic. Your dyslexia has little to do with that; it just means that all you know about preterism and amillenialism is what you've been told by someone whose biases are unknown to us. I don't know if your source wrestled with who the genea that will not pass away before Mat. 24 is fullfilled is. I don't know if your sources examined the writings of Justin Martyr or Augustine. I don't know if your sources have dealt with the fact that dispensational premillenialism was an unknown until it was taught by an obscure Anglican separatist itinerant preacher in the 1830's.
In short, I can't tell if your sources know anything at all beyond what they believe.
You forgot to mention that you don't know Scripture teaches premillenialism.
