For the argument part, other member has made a better demonstration.You needn’t argue with me. My degrees are in engineering physics and astronautics.
But I will ask, what the f-word is the diploma flashing about? Your NOT having a degree in the ship building industry did not stop you from arguing in warships and maritime engines, your NOT having a slightest education of Chinese history did not stop you from sprinkling saliva on the subject of what China should or should not do.
Besides, everybody here including me have degrees in various disciplines, so watch out your mouth when you enter some other subjects.
