I hardly think a degree in Communications would mean anyone had taken Physics. It's generally not a specific science requirement (although anyone could take it of course. At least at BU, you had to take science classes if it wasn't the area for your major, but they could be in anything, e. g. Geology, etc.), whereas Freshman Comp or its equivalent is required pretty much anywhere for a degree.
We do, as a society, tend to pile onto politicians for gaffes that people make all the time and generally are harmless. It's not necessarily fair or correct.
