So what if we all end up mixed race? What's the big deal?

hmm... this is pretty textbook white supremacy. White supremacists fear their identity is under attack. They have a paranoid sense of annihilation which they look to blame some minority group for.

This is very different to identity politics. Identity politics is about minority groups wanting to live with dignity - it's not about the preservation of their identity, it's about trying to overcome the hatred they endure because of their identity.

Do you seriously believe that the UN do not understand these things better than you?

Like long range weather forecasts they have got a great deal better in recent times.

Immigrant birth rates are higher now but will reduce and then match our current levels over a relatively short time. There is plenty of past experiences to indicate that is a very confident prediction. It's also common sense.

That's not what it said at all. The forecast was for a marked slow down between 2050 and 2100 with it peaking then and stabilising. No responsible forecast has ever indicated a growth rate that would take us towards 20 billion. The current level is 7.7 billion. The forecast is 9.7 by 2050 and around 11 billion by 2100. These are big numbers, but manageable with planning and the use of technology and science. There is just no need to panic.

The movement of people is an entirely separate subject. It is though completely wrong to assume that just because the genetic make up of our fellow citizens will continue to change, just as it always has, that means there is some kind of threat to us by way of decreased living standards. Everyone wants high living standards, including any new arrivals, and it's them whose standards will be raised and not ours diminished. We just need to make sure that new arrivals are welcomed and integrated, just as we have done with previous waves.

Challenges are there to be faced and overcome. They are not overcome by sitting at a keyboard complaining about how awful things are going to be. We will only be defeated if we surrender our well earned reputation for tolerance, good humour and kindness. Other nations respect that and we should be flattered when people want to join us. Make them welcome and train them to be like us and before long even people like you will wonder what all the fuss was about.

So diversity is good provided everyone is the same.
