That's OK, chief. I don't do very well around people who lack basic human empathy, anyhow. The Exxon suit was not thrown out; it was sent back to the NYC district court. It's still in litigation. That only leaves like 849 lawsuits you haven't accounted for.  

Exxon's scientists told management that AGW was a serious problem at about the same time that science in general figured this out, in the late 1970's-early 80's. But . . . Exxon-Mobil CEO's, including the current Secretary of State, told stockholders another story altogether . . . for like 35 years.

And THAT is one serious crime. Ot at least serious malfeasance, as is being argued by people who know a lot more about lawsuits that you do, Chief, including the AG's of 17 states and a group of Exxon shareholders.

Lying about matters of great social import is not protected speech, no matter how many continuances and motions Exxon's lawyers throw up to obscure the matter.
