Appology accepted! Don't worry, If it's the person that I am thinking of, then yes we do ignore him.
It's sad, really, that some feel they must impose what little knowledge (for that's what is is now - little and out of date!) on the others around him.
Unfortunately a little knowledge can be a dangerous thing (ie. he can make it hard for all concerned, not just the controllers, but other pilots included). But I think we can recognise his voice and accept him for what he is.
Must have a small member or something, trying to make up for it with big words!
