> Slander/Libel, in the UK where this isn't, has to contain falsehoods.
Be careful this is a dangerous interpretation of UK law. Slander/Libel must contain some element that the person doing the saying/publishing cannot prove in court. Note the burden of proof lies on the person saying/writing rather than the person sueing.

sorry, yes, I am aware that the burden of proof is on the accused slanderer, since these are civil rather than criminal cases. I appreciate that that wasn't clear from my original comment.
People can launch all kinds of suits which can't possibly result in victory. The courts won't try a case before they try it to see if the plaintiff would win.
Can people in the US really sue each other for reputational damage even for saying only true things? If so, that is bizarre IMO.
