"A" is singular. Are you ignorantly stating there was only one "frivolous lawsuit" ?
He is ignorantly stating so much - including the fact that “frivolous lawsuits” can still cost REAL MONEY. It’s as if HG thinks that frivolous means cheap. It doesn’t. In fact, frivolous lawsuits are brought for one reason, to financially ruin the subject of the suit even though there is no cause. HG ignorantly makes the opposite case, and yet, he has not the capacity to understand it.
As you know from your screen name, there is a perversion in Alaskan law that allows for these kinds of suits that are not applicable to any of the other 49 states. This is beyond the Liliputian mind of many around here....
