I agree. It is definitely not an issue of phrasing. I have had so many discussions where people fail to comprehend the concrete differences between converse, inverse, contrapositive, especially in relation to causality/mechanism. To me this seems to be especially bad in political discussions on facebook, but also, is even a critical issue among some PhD level synthetic organic chemistry students - where "mechanism" is a very important concept.

I am certain that these people would miss this problem on a first pass, second pass, and maybe even third or fourth pass.
