:::::You leave redundant and misapplied template warnings on my page, accuse me of being "fanatical", and now whine about "incivility"? Please. 

 :::::You misunderstand WP:RETAIN. The guideline directs us to go in search of the first major contributor if an article has not "evolved sufficiently for it to be clear which variety it employs". This one clearly had evolved sufficiently, so your search for the "first major contributor" is moot. By the time you arrived with your stylistic preferences, the article had evolved sufficiently for it be clear which variety it employs. If you had only been willing to abide by WP:RETAIN, you would have left the spelling of -ize words alone.
