This is again, a classic emotional ‘shut down’ phrase indicative of a disrespectful communicator. If thought about logically, why would another human being have the right to dismiss the emotions - thoughts, hopes, dreams, beliefs, worries, stress, sadness or wonder of another? In relationships without respect and therefore good communication there is a constant attempt to convince the other partner that “if your beliefs are not the same as mine, then they are stupid, senseless, unimportant, irrelevant, unnecessary, frivolous, over-reactive, pointless, wrong, or absurd. There is arrogance to an individual telling another human being that what they are doing or thinking is silly. That is simply one person’s opinion and respectful communicators would feel badly patronizing their partner.
