Why do you single out Christians by saying "that's what Christians do" when you already stated "A Hindu in the equivalent situation would want his Christian spouse to share his"?
The disagreement we're having here fundamentally is that you want to portray this as an argument about how liberals "don't even understand" faith, but the content of your argument treats faith as nothing more than an excuse for the husband to dominate the wife. When a Christian husband disrespects his wife's Hindu faith, you support the husband. When a hypothetical Hindu husband disrespects his hypothetical Christian wife's faith, you support the husband. What's the determining factor? Spoiler alert: It's not faith.
So please, just be honest about the reason you really support JD, about the real thing liberals "don't even understand": that women should be subservient to their husbands.
