You're basically getting offended at BBC reporters speaking too politely. Next thing you're going to expect them to talk like run of the mill chavs because that's how people actually speak, innit bruv?
Again, don't turn the table. You are offended by "pregnant women", and you push for subtle dictionary changes. Changing the words, to change ideas (i think Lenin created that concept).
Just assume it, instead of constantly doing psychological projections on others.
