I find that some discussion with the "logical" type can be extremely difficult, because we (I include myself in that category) often don't realise they have an emotional response. I think this is also behind the OP I don't want my emotions to be validated statement. Anything the other does even validation is emotionally rejected (often even a complete surrender, I.e. "you only say I'm right because you don't want to argue anymore).

I noticed this sort of response in myself after getting some communication training. For myself this triggered me to very consciously pay attention to me having an emotional response (obviously not always successful) and the try to deliberately validate the others perspective. Interestingly I find that this also helps me to actually understand the other person more and lowers my "emotional defense response".
