Joseph: Today’s Chumrah of the week club doesn’t define Judaism either. Remember, Chumrah and Chamor have the same shoresh. Things may have been a bit lax years ago, especially in lack of understanding in kashrus matters relating to food production, i.e. things like candies, etc.
We are probably headed back to those days, since certain subjects, like science, has been assured in many Chareidi schools. Without that knowledge, it’s back to the 50’s ignorance.
Have you noticed that Kashrut administrators that deal with food production mostly have University educations?
