Here's an example of a kosher kitchen. One side is for meat, the other for dairy. They can never cross. It's miles beyond what God intended, total nonsense.
So you have an issue with how folks arrange their own kitchens in homes you don't abode in.
I've been to Jewish homes for meals and didn't care or see reason to nitpick about their kitchen and they didn't God bother me christian style..👍
Whats your view regarding these christians and alcohol.. Are you OK with christians that don't allow alcohol in their home,?
