I'm referring to the entire chemical industry. This thread is chock full of people saying "Teflon = Bad" when it was manufacturing safety and (maybe) the practice of ignoring warnings and grilling with teflon pans that were bad. It's an amazing material and it would be a shame to see it memed out of existence.
This kind of thing has happened before. If we (USA) hadn't stopped rolling out nuclear in the 80s, we'd be off coal/gas by now, instead of maybe several decades from now after pumping ungodly amounts of CO2 into the atmosphere. Anti-vax and anti-fluoride need no introduction. Agrotech probably receives the most hate per unit of actual sin -- it's an odd week that I don't hear someone patting themselves on the back for choosing a product that is almost certain to be worse for the environment because an upscale vendor successfully applied misleading differentiation tactics to convince them of the opposite.
Indiscriminately attacking progress and throwing the baby out with the bathwater has become a national passtime that shows every indication of getting worse before it gets better. Teflon seems to be another instance of this trend.
