Larry, just because people disagree with stuff and are not afraid to put it in writing doesn't mean they are trolls. krw is not a troll, J. Clark is not a troll? Trolls always use fake names, are not at all interested in anything related to the newsgroup, and often work in teams, and/or take on multiple personalities for the sole purpose of disrupting a group. 99% of the time you can spot a real troll easily by the name, and the content of the post. If you think these two are trolls, you need to think harder.
It's true that ignoring trolls, or anyone you disagree with, will make your on line life quicker and easier... But boring as hell.
