Please hear me out.
I have two dcs, both dual citizens who have lived in the UK all their lives. When the census came, there was no way to put two citizenship on the form so I asked them what they wanted me to put. One said british, the other his other citizenship. So they clearly self identified/realted more as as having different citizenship iyswim.
I also have a cousin who mixed race. Her mum (my aunt) is white but her dad is black. But she has never had the opportunity to actually chose which race she is (the way my dcs could chose their main citizenship). She has always been considered black. That's despite the fact she has never lived in her dad's country/africa and was actually raised by another white aunt (having become an orphan). She doesn't relate to 'black culture'. The only way she feels 'different' culture wise is her hair - because she struggles to find a hairdresser who nows how to deal with it.
So my question is: why are people not able to chose which race they are? What if someone who is mixed race feels more like being white than being black (insert any other race there, it doesn't really matter)?
