I have researched him previously. He is a lawyer who worked for an energy company in Texas, so it's reasonable to expect he doesn't have experience with defamation law.

Amazing that he doesn't know something as simple as the different between slander and libel, and has a law degree. But I'll believe you. I don't want to get into a side issue when it's not relevant or could be a distraction.

Lets just note that it's not slander, and if he means defamation:

Untrue. In order to be defamatory, the statement must be untrue. If the statement is true or substantially true, then it is not defamatory, and the case is over.

Damaging. In order for the plaintiff to prevail, the statement must have caused real and substantial harm to the person or business. The plaintiff must present evidence of the substantial harm done.

Knowingly false. The plaintiff must also show that the defendant knew the statement was untrue, but published or broadcast the statement despite that knowledge.

I'm out, the whole event is his cause, coming here, shouting, name calling and attacking our group, tossing out insulting comments and attacking many different individuals personally. I still can't understand the logic, irrational behavior or motivation. Nothing makes any sense? I just look at "WHY" and the actions seems terribly irrelevant to any goals? I'd like to know what's actually behind someone coming to a forum, kicking a hornets nest, when he's not even a member of the club? What's the motivation?
