As above mixed race and dual heritage are not the same thing. They are different things.
My mums parents are Irish and Greek. My dad is Asian. I was born in Ireland and live in England. My heritage and cultures that influence my upbringing are more than 'dual'.
I am not a fan of mixed race. But mainly because I don't like race at all, as a social construct. Some of the suggestions from people on here from peoples employers are that ridiculous I would find them offensive.
Don't like BAME. It makes me think you are either White or Black or other.
If people are describing me I would rather they used my skin colour to describe me. 'Have you seen Whiskey?'
'Who?'
'You know. Tall, dark hair, dark skin...always talking about her dogs'
But then I think mixed race works well if you are talking about groups. I am not a fav of POC, but can see how it could be useful
'How many people of colour did we consult with on our new diversity training?'
'None'
'When we decided to tell people these were the acceptable terms that should replace mixed race, how many people who are mixed race people did we consult'
'None'
I don't find them offensive. But I don't like them and accept is society we still need something.
