I think it is really accurate. They really are like this. I actually had a female aquaintance who used to argue against the military and against war with me like this, and she would get very agitated and irrational – unable to understand logical relationships like greater than or less than, or less probable and more probable. Everything is about the moral equivalence – there was no possible condition under which war could ever be justified.
