 You are clearly an idiot and fail Wikipedia:Competence is required - what sort of person removes city ports from a category named "Ports by City" because of some footnote left 8 years ago ? And then re-instate the message claiming "consensus"  

 You clearly don't understand the first thing about categorisation, and have shown that you are incapable of thinking independantly . 

 I can't believe someone as stupid as you could actually exist. But you've proven it true. Please stop editing. 

 Idiot.
