I can not find the link as my Google-Fu is weak today.
CFC's are on the way out but only recently in the grand scale of time and things.
Aerosol propellants were not all CFC's. Many were other inert gases as they were easier to use and far less expensive.
In my limited ability's/knowledge I can not offer up any argument based solely on fact. I can however use my personal experiences from conversations with engineers and other very knowledgeable people who have refuted a lot of what is being force fed to the masses.
Follow the money. Follow the huge grants. Look a what is to be lost and gained in all of this madness. Who is saying what and why. That is a serious way to address what we read and believe.
The big one to me is that they are more dense than air, and have no way of getting to the stratosphere. All of the research was done in laboratories, artificially combining CFC's with Ozone.
