Vert strange, Mr Red.

"You know there are two sorts of people in the world - those that divide the world into two sorts of people, and those that HATE MARMITE."

By saying "There are two sorts of people in the world" you clearly identify yourself as being one of the sort of people who "divide the world into two sorts of people".

And that means you cannot possibly be one of "those that HATE MARMITE."

But then in your later post you indicate that this is not the case...
