Gender and sex have always been synonymous with one another until activists started redefining it. It's a flat out lie to say that sex and gender are separate. There are men that are more feminine and women who are more masculine, it doesn't mean they are the opposite gender/sex. Being a man or woman is not a feeling, it is a state of being. You are what you are. Learn to live with it and stop trying to force your ridiculous queer cult onto people.
It was proven with the grievance studies that most of the research regarding transgenderism and queerness, are written by activists and based on absolute non scientific nonsense. The link you posted for "confusion on sex and gender" is a paper that literally uses other activist papers as it's research.
"To dismantle rigidly binary sex categorization, we propose the adoption of a biocultural and queer theoretical approach to forensic sex estimation and in sexual dimorphism research that challenges heteronormative assumptions, questions typological two-sex categorization, and combats the presumptions that gender and sex are stable, independent entities that convey universal meaning. Relatedly, the expansion of trans-oriented research, which is supported by 95.8% of respondents, will further improve methodological accuracies." = gender activist word slop
If you've done the research like you've said, rather than parroting activist papers posing as scientific literature, then you would know this. But I guess your cool with turning children into confused, life long medical patients. This is the new conversion therapy for gay kids.
