In other words: "When confronted by contemporaneous Arab evidence directly demolishing my previously held anti-Semitic beliefs, based on long discredited and disproven information... I'm opting, no reasons given, for my previously held anti-Semitic beliefs, based on long discredited and disproven information." Gotcha.
"I couldn't care less about what Arab sources say." = "I have no rebuttal. The sources -- all Arab; all anti-Zionist -- say what they say; and nothing I could cocneivably post would ever change that."
" I don't know what their motives are for saying what they say." = "It's all some dire, nefarious master plan of those dastardly, demonic JEWS, I tell you! The JOOOOOOOOOOOOOOOOS -- !"
Good lord, kid.
Okay. Alouette was right. I'm done with you, now. :)
