Any conversation sits on the premise of quality interaction between the parties involved. This quality assumes competence and good will, each having to be over a certain minimal level depending on the subject discussed. When any of the involved parties determines that there is not or can not be enough competence or good will, then normally the discussion should either cease or switch to another level. (At most, you may explain your decision ...if you have that minimal level of respect towards any of the parties involved in discussion, that is.)
