What I don't have a firm grasp on is how to explain it to others, that is all.

That is in my experience a sign of not having a firm enough grasp on the subject matter.

If you had a single grain of faith in my intelligence you would be able to figure it outbut you don't your completely and unfairly biased against me because I am having difficulty explaining it in a manner that you understand.

Please learn to restrain yourself and refrain from hurling insults.
