Why take this personally? This is not a personal battle. It's isn't about disliking the way a person communicates, nor about it being right or wrong. It's about the way Wikipedia articles communicate, namely, in a way that hopefully minimizes friction for their readers (whom it's there for - it's not there for the editors), without compromising on accuracy. I would think editors really ought to be able to distinguish "I like this word more" and "I think this word is best for readers".

You asked why there is resistance. I summarized a portion of their argument, in blunt terms, as that makes it clear why some people might be upset.
