Is there a brain defect that causes some to think that slurping of any kind or eating with your mouth open near anyone else is in any way socially acceptable?

Is there a brain defect that causes some to think that slurping of any kind or eating with your mouth open near anyone else is in any way socially acceptable? I wouldn’t say I suffer from the thing in this article but at the same time, I don’t want people to eat like a wood chipper either. Where does that put me?
