Man...I've never experienced or know anyone who experiences things like this. These are some dysfunctional situations for sure.
No kidding. When my wife and I got married, I told both sides of the family that if they wanted to say something during the wedding that was great with the caveat there would be absolutely no mention of religion, God, Jesus, Allah, church, any "holy" book, or prayers. Our officiant was secular as well. I assumed my stance on religion was pretty clear and, while I am sure some were annoyed, I wasn't shunned from Christmas dinner.
