I am sorry, but the English language disagrees with you.
"Although everyone is well aware of federal law so if you have a barrel lenghth that size you are an obvious moron."
is the sentence in question. It is very clear according to English grammar rules, that 'you are an obvious moron" belongs to the condition "if you have a barrel length of that size." Unless redmanfms indeed does have a barrel length that long, he is obviously not the target of the "you are an obvious moron" clause. And if he does have a barrel length that long, knowingly, he is a moron. Truth is the ultimate defense.
