I think the difference between gender identity and gender traits/interests is interesting and complex. I'm also not sure I'm going to word this well
but just in regards to the latter, I wonder if people who see themselves as having some gender incongruent traits/behaviours/interests have two ways* of making sense of this. The first is to reject gender essentialism and to interpret gender traits as socially constructed and irrelevant. The second is to interpret this as indicative of intrinsic gender characteristics and to see themselves as more identified with the opposite gender, or a mixture of the two. It's more relevant for the growing number of people who either describe themselves as "just not that feminine/masculine" or non binary rather than the less ambiguous cis or trans identifications. What I find an interesting question is what are the differences and similarities between those two groups, and indeed is there something more fundamental going on or how much does it relate to different ways of interpretation? But tbh I don't really think I'm qualified to say any more. It's just interesting because I'm not sure I know of many people who see themselves as all feminine or all masculine.
But then as someone else said, it's complicated because identify and personality/traits/interests, gendered or not, are so linked it can be hard (if not impossible) to pull them apart.
All I do know is that if my daughter aged 6/7/8 came up to me and said "I think I might be a boy because I prefer boy things" I would listen to them, let them explore it, and non judgmentally suggest that they then do whatever activities they want, dress however they'd like, hang around with whatever children they'd like etc. and see where it takes them. I find it awful when people tell children that they can't do or act in ways that are seen as opposite gender traits
, yet at the same time the idea of labelling someone as trans before they're developmentally capable of abstract thought and pulling apart interests and identities really doesn't sit well with me
