Popa, it sounds a little stupid to rely on a hachsher if they the,selves only give it an approved status, not a full one. That’s not politics, it’s simply closing your eyes.
Amazing. Simply amazing. It is stupid to rely on a hechsher when the approve something. I think you’ll need to elaborate on that one.
But before you do, I’ll let you in on a secret: All hashgachos do it, even on things that they actively certify. They have lists of ingredients that are permitted, even though nobody certified the manufacture of those ingredients. American hashgachos call those “Schedule A ingredients”.
If you don’t trust the stuff on their approved list, you cannot eat anything on their regular list either, since it may contain ingredients from their approved list. Certainly in an establishment certified by the London Beis Din, they allow the kitchen to cook with things from the approved list.
