Are there citizens of the UK who will not accept a mixed race child in the Royal family with the birth of Harry's child?

Most people in the UK do not worry about skin colour and do not classify people as "mixed race". That is an American obsession not a British one. Many people in Britain were unaware of Meghan's ancestry until they saw her mother on TV at the wedding, and most don't care.

MOST not bothered in 2019...Some of us are BROWN too ffs..

I am not bothered.They seem to have endless kids

It was Dianna I disliked,even hated

They cannot not accept it.

I don’t know exactly by what means they’re going to reject the kid. They’re stuck with him or her whether they like it or not.

Very few. Most of really don't care about race, children being mixed race - we judge people on their actions and words and not on the colour of their skin.

A few may be racist, but they're very much in the minority.

There are some who won't, but then there will be many who do accept a mixed-race child in the family.

Many people are unaware of their biases and prejudices, though. They say they don't care, but they do harbor some hidden racist assumptions.

Yes there are some but, there would always be some, who would not accept it. in the same way that they wouldn't accept a blond, Buddhist, tall, short, fat or thin person. That's just the way things are, you cannot force people to like or even tolerate some things.

Not really , I think its an American problem mostly.

Then you do care! the UK will accept meghan and harry's baby, why would'nt we?
