Like I said, any term can be meaningful when you're talking about political theology, but terms quickly become meaningless when you get down to the details.
Again, let's take a favorite here, "equality." I get what it means on an abstract level. What's problematic is figuring out what it means in execution. Do you mean equal outcomes? No? Then how about "equal opportunity?" What does that mean in practice? Does that mean that everybody gets the same (inevitably second-rate, mediocre) level of education? Does it mean that kids are taken from their parents so that kids with wealthy, smart parents don't get a leg up over kids with stupid, poor, abusive parents? etc. etc. etc.
