My father was a Mason. My granddaughters are Mormons (separate sect of the the LDS). Big difference in many, many ways. Looks good from the outside, big problems on on the inside.
There are ‘big problems’ on the inside of every human organization. And many of the people involved in those organizations aren’t touched by the problems at all. The value that they take is bigger than - and beyond - the mere institution.
None of us knows what religious or spiritual viewpoint might be useful and valuable to another person at any point in life. We may wish otherwise for them - I might, for instance, prefer that my child not become a Roman Catholic or a Mormon - but it’s ultimately none of our or my business. As long as people are not involved in illegal activity or coercing others in criminal ways, I have to trust that God has ways of getting to individuals that I’m not willing to second guess.
If we start deciding that a particular religion offends us and we must do something to ‘stop’ it, where will that end? We live in a culture right now where many believe that *any* religious belief is a ‘mental illness’.
