No,I think this is quite interesting.
Sex, and gender used to be used interchangeably by most people. Now with all the gender nonsense we need to remember to be very specific and use the word sex instead.
But getting back to the thread. Small children like to put things/people into categories, so mummies/daddies, cats/dogs. I would suggest that 99% of the people writing on mumsnet grew up at a time when sex was unambiguous, we weren’t taught to be inclusive all the time.
I also have an unconscious bias that dogs are male and cats female. I owned a big dog for many years and although a she, people would think she was male if they couldn’t see her undercarriage clearly.
I think we all have inbuilt associations about the sex of the dog depending on its looks/breed.
So to me a stocky bulldog would instinctively be male, and a miniature poodle would be female. This is the millisecond thought that flashes in my mind, before I correct myself and notice things like a pink lead.
I wonder if we wrote a list of all breeds and had to assign a sex to them on just the feeling they arouse, I personally think social conditioning would make our replies similar.
Its along the same lines as what is your automatic reaction to the sex of say a nurse, surgeon, engineer?
Border Collie anyone?
