Being constantly upset about such a global issue will not make it magically go away (even if you vote Reform) and will just make you bitter. Being frightened of people with a medieval faith ignores the fact that it will dilute and diminish through future generations as it has in Christian UK (no offence if you regularly attend church).
The UK and the world will always change. It always has and the UK has, of course, played many a leading role in shaping global changes for sometimes good and sometimes not so good results.
