Agree with luckygirl No one knows the reasons, if there are any, why the family is estranged but nevertheless feel able to put their views on a public forum.
There is a long and supportive estrangement thread on here so it’s not unknown and the royal family are no different to anyone else, other than they live an extremely comfortable, but public lifestyle.
I don’t follow what’s going on in their lives but remember recently when Harry flew over to the uk that his father took a plane elsewhere, Scotland maybe? so they never met. He knew his son was coming over, but he ‘didn’t have time’ to meet him.
Let’s not judge what we don’t know about.
