In the past, when it comes to the royal family, we were appointed so high that we couldn't reach it, and we still wondered how they lived. Maybe some people can't even think about it. With the years when Princess Kate became a civilian princess, the distance between the people and the royal family can be closer. It will make more people feel that this country is warm and loving, making this country less mysterious.
For example, before Princess You got married, her object was not that kind of person with a distinguished background, but also a civilian, so now Britain does not pay attention to this lineage. And all the people in Britain don't really accept these two civilians at ordinary times, because more than 50 years ago, there was a Princess Margaret who wanted to be with a civilian, but at that time he was strongly opposed by members of the royal family, and finally their marriage was not so satisfactory.
There is also a son who gave up his throne because of his earlier love. Besides, he married a divorced woman. At that time, many people did not understand that he could not give up the throne because of a divorced woman. He is still a civilian, which is not worth it. But in these short decades, such great changes have taken place, which really makes it difficult for the British to understand.
However, Britain is still relatively conservative, and it is a bit strange to think so, but in fact, other countries besides Britain have long accepted such a combination, so it is normal for British nationals to accept it now.
