What if you called a shunner out at a funeral? Is that any harsher then them not talking to you or treating you unkind at a moment of grief? What would be wrong if you stated out loud why a family member isn't talking to you? Wouldn't that bring shame on the religion as it well should?
Some bad things were said by the witnesses at my mothers funeral. My new stepmother behaved badly at my sisters funeral. I didn't need to point it out as it was so obvious to all of the non witnesses present.
They do well enough to bring shame on their religion, I don't need to be the one outspoken person in a crowd bringing shame on myself. There's a proper time and place for everything and I don't think a funeral or someones wedding would be the right time and place.
I understand what your saying and I agree people should stand up for themselves. I understand what others are feeling and I'm sure that someday they will reach a breaking point or a comfort zone and speak up.
