I think they're meant to be quite liberal. Agree it's a bit odd that she was so pleased that they'd both got their new girlfriends pregnant without even meeting Jackie but a family row probably wouldn't have suited the episodeI think Jackie definitely would have been OK with non-Jewish DILs. I’m not sure she would have been OK with her sons knocking up their girlfriends a) without a wedding and b) before she’d even MET them It just seemed so out of character to see her go “Oh OK then!” instead of slapping the boys around the head, etc
