I think it might be that some terms are ambiguous, and people have either been tripped up by it, or have exploited it, so the next time someone brings it up, they are on guard.

And like "truth", you have "justice" and "freedom".

For example, you can have a judge and a defendant both talking about justice with two radically different mental maps in their heads. And a year down the road you talk to the defendant and he might have updated his mental map and ask for clarification.

The one that annoys me is "advertising" which people view as benign pictures showing up on their browser, but might really be extremely invasive surveillance and profiling of everyone.
