So you know these people? I hope you will immediately inform them of the existence of something called ‘vitamins’ which I am sure will make their lives much easier than depending on restaurants for their health.
Then perhaps when they can find nothing but a Dunkin Donuts, salad bar, etc. on the road they will not die of iron deficiency.
The use of extraordinary circumstances and exceptions, including guilt trips with pregnant women, to do away with standards in Catholicism is from Hell, not the Lord.
We are to live our Catholic lives in the world when we are not nuns and monks, and to do so unashamedly. To seek to remove Catholic culture because it troubles some people is the exact technique that has destroyed it in so many places, and removed God from public life. The Lord -owns- public life. It is His too. We are to live devoutly within it.
I wish to see many, many restaurants practicing their Catholicism.
