I can't really sympathize with the view that we shouldn't sort people among any dimensions, or that there's no need. (I'm not even sure conscious effort is enough to stop all the unconscious sorting my brain is constantly doing anyway even if I did want to get rid of it all--though I certainly want to get rid of some, and I've more-or-less beaten the less biological things like sorting people based on fashion or vocal pleasingness.) In this particular case when you find a topic, or a set of topics, that you can't seriously discuss (even if you both disagree!) with a person because they immediately become offended, you've found a barrier to forming a deeper relationship that is in essence just the same barrier that's formed in any situation when one party stops listening. I'll agree they still may be worth your time due to their ranking on other dimensions, but there will continue to be at least that one barrier. Perhaps over time that barrier might even break down--I really believe the purpose of argument isn't to convince the other person right away, but to plant the seeds of differing thought for them to think about when they reflect on their own beliefs later. (Which brings me to a problem with people who don't seem to reflect on their state of mind and their world view very often, but that's another issue, and in any case such an observation can be hard to measure from the outside so it probably shouldn't be used as a dominant sorting key.)
