@Gojira_101 You or your father need not worry about Lars taking the thread of topic.
Most who visit this site regularly are familiar with the content of Lars' posts and don't even feel the need to read them. Telling people here to ignore Lars is like telling people here to ignore the GB.... you are preaching to the converted. Some like to read what he says just to refute him, kinda like reading the WT just to find the errors in logic. But please understand that Lars has not said anything here that he hasn't said before, and his posts have not really taken away from the original discussion.
In saying that, it is a shame that a relatively simple issue, constantly gets clouded by pages and pages of irrelevant information.
