You're making a purely semantic argument, concerning some very common words, which I actually consider to be somewhat rude. It doesn't seem to be the case that you did not understand the intended meaning, but rather that you are deliberately choosing misconstrusion. If you don't think that there is a well-understood sense by which "abstract" means "not real", then that sounds like an argument that a dictionary or encyclopedia would be better-qualified to answer than myself.
