I was asked if I would like to hear about their religion and I did. When they had explained their tenets, I politely declined. They went their way and I was never bothered or my decision questioned.
The one thing I always felt was the respect they had for me and my family. I know, also, that many of other faiths were exempt from the draft while carrying out missionary duties. The LDS Church custom of asking their members to take missionary assignments after completing their secondary education predates the establishment of the draft.
Shame on you, Mr. Trudeau.
