I remember a lot of discussions during the 1960s while living in the old VLA subdivision. The Veterans Land Act was a great force against organized religion. Why? Because war veterans got land to build on to create neighbourhoods with no religious distinction.
How great was it? My mother warned me "never be alone with a Catholic priest." We weren't Catholic. This was at the end of that decade, but the word was out.
My father was United Church and my mother was Anglican. So we ended up going to the Lutheran church. Why? It was closest!
When I decided I didn't believe in an invisible old man in the sky and declined to take the third year of Sunday school which would end with me becoming an official church member, my parents agreed with my reasoning and left the church with me.
The lesson? When people aren't raised in religious ghettos they see more, learn more and are freer to make the best choices for themselves and their family.
