lol, I don't know if you're seriously concerned or teasing, but I have never understood the G-d formulation. Clearly some people believe that saying God is somehow wrong, but I don't believe that. God is my friend. At least I hope so. And the God I believe in is certainly not so uncharitable that He would find an innocent mention of Him somehow wrong.
It wasn’t the in vain thing it was sarcasm over snowflakes hearing the word “God” and getting upset about recognizing any power greater than socialism, their god.
