I doubt there is much difference in the propellants which I actually did address by pointing out that the change came about because “the man in the street” had been propagandized about CFC alleged dangers.

One can hardly tell patients too much and it can hardly be too simple when dealing with scientific ignoramuses.

Right there you join those scientific ignoramuses and Know Nothings that you look down upon.

If you bothered to do the research, you'd discover that there is a major change in the propellants, inactive ingredients, impurities, extractables, and leachables. That ought to be simple enough for you to understand.

...I actually did address by pointing out that the change came about because “the man in the street” had been propagandized about CFC alleged dangers ...

The man in the street had nothing to do with initiating the change.
