Your insistence begets your interlocutor’s (my) resistance, acquiescence, or consternation. You believe that P must be the right way of proceeding or Q is the right picture of the world and that we should act based on P or Q. And I react to your forceful, impactful words either by fighting against them (resistance), by giving in too easily yet against my will (acquiescence), or by displaying my alarmed confusion (consternation).
It is possible, of course, that you are right about what you say, but insistence itself is always in the wrong.
