Have you ever encountered it?
My daugher recently invited her non-LDS friend to a church dance, and her friend’s mom said no. Because she doesn’t like Mormonism. I can understand not wanting your kids to attend a church activity in a religion you don’t agree with. But a dance is pretty harmless. Especially when you consider the standards the church expects the youth to uphold.
We had neighbors when my kids were small who wouldn’t let their kids play at our house. Because we were Mormon. They never told us that, but they told my niece, who was living with us at the time. I didn’t care much, I let my kids play at their house all the time (they were born again types). I remember they did let their daughter come over for my daughter’s birthday party. And I remember her dad coming into the house to get her, looking agitated, like he thought the devil was going to consume his soul at any moment.
