I am with TTT here, one of the AB farts.
Sex can be defined in scientific parameters being all about the sex chromosome.MALE or FEMALE or abnormalities of the sex chromosome which invariably causes medical conditions e.g Klinefelters Syndrome and Turner's Syndrome.
Sex.....simple, clearly defined,
Gender is what you want it tobe, what is in fashion, the vogue something to are the insignificant...significant and worryingly enough coming into vogue.
I will respect homosexuality as a concept.........but will never accept it.
As for the genders, there is no scientific evidence at the moment in genetic or biologically hormonal data..,,.....one just says what one feels, even as young as secondary school and it is becoming more common to accept this concept and even more worrying for the modern parent in particular to nurture it.
