I'd have a hard time presuming anyone to be completely rational. But I'd have an even harder time understanding why I shouldn't point that out to someone who (presumably; due to them being here and all) wants to be more rational.

About your second point: I'm probably a bad choice for identifying your conformity filters due to the rather big amount of time I've spent at salsa and tango courses. Time which takes gargantuan proportions when contrasted to the awfully little time I've spent in Cthulhulian sects.
