for some people I just think it’s better if they don’t. My father is getting up in years and quite frankly for his age and health he is better off been delusional. It is what it is .
That's the way I feel about my parents as well. They hopes to see their dead loved ones soon and it helps them cope with the inevitability of death.
This is why I don't do anything to try to convert my parents. However, if they try to push their ideas onto people in the public ministry, well, its fair game. They are open to ideas and arguments which could ultimately burst their bubble at any time.
