It not dramatic, simply the truth. What is so dramatic that I cannot fully understand somebody? I can perfectly live with that. I cannot fully understand you and I cannot fully understand the author. The author has a huge part of their life I cannot understand. Since I have children I can for example now better understand other parents, but I will never fully understand their individual struggles.

That is just acknowledging individuality and diversity. I will still demand stuff from those I cannot understand well. For example abiding to laws etc. Individuality does not automatically imply immunity to judgement or special treatment. You seem to think that.
