Your post above directly confirms what I asserted in the first place. Your tendency to become unpleasant and abusive when a valid perspective is aired. If it's your reflex here, it means it's a tendency. Can you state categorically that you don't ever react that way within your relationships? Substitute 'moron' for 'mental illness'. So often the need to label others, but to idealise your own behaviour. These are merely observations made over time. Why do you feel the need to abuse and rant at any perspective that doesn't match with yours? That kind of behaviour will lead to a deterioration of any relationship.
