Yes but 'sex being on a spectrum' was when I was 14 in 1972 and knowing trans people is from a couple of years ago but you have conveniently put the two at the same time, are you a Journalist?
Nobody will convince me that humans aren't on some spectrum between male to female and the clincher was when a baby nephew came into the fold that we looked after nearly daily.
From a baby he was different, very gentle and he would always go for stereotype female toys no matter how many times we would lead him with stereotype male toys & behaviour, anyway, he is the family member that is transgender. We all tried so hard to take female traits out of him with no luck and it wasn't a surprise when he eventually announced it.
Are you implicitly suggesting the 'trans' peole you know are deluded because they have nothing to transition to?
You are still confusing sex with gender stereotypes.
Its part of the problem that you believe that a human born with a penis who goes for non stereotypical toys or exhibits non expected behaviour isn't actually a male but is on a sex spectrum closer to a woman.
You perhaps don't approve of the medicalistaion of such matter but the institutionally 'approved' response to such matters increasingly is to put the child on puberty blockers, then cross sex hormones followed by surgery to create an approximation of the genetalia of the opposite sex.....
.... having caused untold damage to the body and mind of the subject which has been deprived of a natural maturation.
I have a family member who was like you describe when he was young.
He's now a married gay man but still rather effeminate in his gender expression.
But he is unquestionably a man not some human on spectrum between male and female.
He didn't stop becoming a man because he likes other men and is more effeminate then most men.
Biological sex correlates strongly to gender identity but isn't the ultimate arbiter of it.
The confusion is that biology is a strong predictor of the average person's behavioural traits so people get the relationship the wrong way around and assume behaviour is conclusively deterministic of your sex.
It isn't....
if you are born male, with male chromosomes and genetalia you are a man.
This doesn't mean you won't be kind and like playing with dolls just on average you are much less likely to do so.....
with your sex, on average, preferring things to people and rough play and competivness to cooperative agreeableness
