Hachi-sama
This is Kawaguchi Hidetoshi. This is my humble answer to the question.
I can't go into much detail here, but I had several opportunities to talk with people who have joined a new Buddhist religion a few years ago.
There were times when they exchanged legal arguments with each other, but as a result, they were unable to understand each other and parted ways on a parallel line.
However, after talking with each other, we also learned a lot. Also, I knew that person was working hard to live with their own thoughts and beliefs. But that was something I could also say to myself. He is still an immature person who is still a young student, but it is said that he is a humble student living with ideas and beliefs while learning and practicing Buddhism in general. It also means believing that each other's thoughts, thoughts, and beliefs are correct.
However, the problem is its “correctness.” Troublingly, “correctness” is relative, and value judgments are also easily influenced by individuals, society, countries, times, etc. Also, what “absolute correctness” is something that cannot be decided at all by self-righteousness or complacency, etc., and since everyone admits it, even if you say “correct,” it can even be naturally overturned if a firm disproof comes out.
What I thought here was, “Whether it's a traditional religion or a new religion, it is important to always rationally and sufficiently verify whether that way of thinking is correct.”
Going back to the story a bit, I think it would be good for both mother and Hachi-sama to be able to discuss with each other as much as possible, estimate the extent to which mutual understanding is possible, and treat them in a balanced manner while properly sorting out the parts they can walk up to and the parts they can't get along with. Among them, I know that if it becomes impossible no matter what, leaving one's parents and becoming physically and mentally independent will become one thing.
However, as long as everyone has “freedom of religion,” I don't think that national power, authority figures, or parents should force their faith, and I'm also considering whether acts based on that faith are antisocial or criminal.
I pray for good fortune.
