I used the term "adversaries" because that's how conservatives view ACFs, as adversaries. ACFs themselves view anti-Marxists as enemies - people whom they not only wish to defeat in matters of public policy debate, but also destroy utterly (even murder). 

It's the same psychological issue that always emerges with ACFs - they assume that their adversaries (enemies) are as hyper-partisan, vicious and amoral as they are themselves.
