A recognition that an editor has
 difficulty in comprehending facts presented to them, 
 made a racist comment intended to insult another editor on a talkpage, 
 problems in conducting research, and 
 a demonstrated bias in editing a particular article, 
do not infringe on WP:NPA. 

That you find these constructive comments insulting is of severe regret to me. Nevertheless I hope they assist you in becoming a better editor. Hopefully on the next occassion when you decide to promote what you think above physical and sourced evidence you will remember how embarassing it was to see that attempt fall to pieces. I am glad to have helped you with that.

By way of being constructive again, can I suggest you actually read WP:NPA, apply it to your own public comments, then when you believe you have a firm grasp of it, come back and we can discuss how applying it to your own work will improve you as an editor.
