Yes, I absolutely do. The concept of women as "emotional" AKA "hysterical" is an old, untrue, patronizing and dismissive stereotype, with a long history of being used to oppress women (sometimes in the most horrific of ways). "Calm down dear" and its close paraphrases are a way of asserting male privilege to ignore a woman's reasoned argument, because she got angry.
"calm down dear" has been said frequently to men, women, and children by both men and women. Also, there is nothing uniquely male about using that phrase in a patronizing tone.
