I suspect there is a second purpose: to try to sabotage the majority's morale by inflating the minority view's volume of posts. Prodigious posting by the likes of Gator make it appear this minority is not as tiny as it is compared to the majority view, which would be YOURS and MINE.
That, I believe, is why the Gators and other dupes post about three times for every ONE post of an opposing viewpoint.
Thoughtful readers notice contents, and give substance more weight than volume. at least I hope that's the case, and based on feedback I've received over the years, I believe is the case, as well.
In other words, don't sweat a large volume of repetitive remarks that don't advance a substantive argument.
