As explained by thackney in the post immediately underneath yours, there's nothing secret about these materials. They're openly available for anybody who wants to know.
So, ask yourself, if this is so, why does there need to a federal law to mandate their exposure?
The answer should be clear: In order to stigmatize the materials and rigidly regulate their usage -- eventually shutting down the industry.
This administration is waging war on fossil fuels. And they don't care whose jobs are lost...or what it costs the consumer.
Thanks for the reply.
