'Our vision is for Brighton to become the first place in the UK where all young people who identify as female, especially those who are absent from other forms of education and support, can find a voice through dance.'
In other words, any young person, regardless of sex. Fine. Just rename your organisation!
I've been thinking about the concept of 'inclusivity' - to include a set of people in, you automatically exclude another set of people out. Otherwise it wouldn't be that set. Potentially it has to be inclusive of the entire human race, if you can't draw a circle around a specific set of people.
If there was a support group for left-handed people to share their experiences of living in a world designed for right-handed people, it would be logical for it to be inclusive of any left-handed person, but exclusive of all right-handed people.
If it included right-handed people, it wouldn't be the same, so it would need a different name. In fact, if it was a group for left-handed people AND right-handed people, including those who identify as left-handed, it would have to be inclusive of the whole human race, wouldn't it?
'Inclusive' is related to 'enclose' and they both derive from the Latin, meaning to shut in. The idea of inclusion/exclusion is present in the word 'inclusive'.
It only becomes unfair exclusion if people who properly belong to the set are excluded because of some other characteristic, like if a group for left-handed people excluded left-handed people because of their race or their sex.
'Sorry, Marie, love you to bits... but... we've noticed you're not left-handed so this isn't the group for you' should not and would not send me into a tizzy of victimhood.
