I should never have downloaded The Guardian app

[Philippus Flavius Homovallumus]

Some use the word gender to refer to a social concept, others to refer to a biological concept. No bonus points for correctly guessing which group I belong to will be given.

No, gender is actually a social construct, different people fit the construct to differing degrees (and that's biological) but under a different gender construct those people would fit differently. For example, in a highly homosocial society homosexuality is a norm and men who are mildly intersex become objects of desire (as they are less threatening to Alpha males) whilst highly feminine women become less desirable than more "boyish" ones. Conversely, we live in a society which has normalised heterosexual relationships and constructed highly differenced genders in support of this which means that intersex people are naturally threatening.

It's like sociopathy, it's only a bad thing if your particular sociopathic tendencies are considered negative in your society.
