When I wrote that, I wasn't aware of the existence of the Nazi wedding venue. I posted what I posted as a hypothetical.
My point was simply that a wedding at a slave plantation and a hypothetical wedding at a concentration camp sight would be equally immoral.
It's good that the concentration camp wedding scenario, in all liklihood, wouldn't happen.
That said, I'm not sure why you are so invested trying to deny the validity of the hypothetical comparison.
