And yes, obviously controversy will focus on the one controversial detail. There are hundreds of other details that are not controversial, so they aren't mentioned.
I don't understand why this bothers you. The world is a controversial place. It's good to document these things.
Hypothetically speaking, let's say you were a famous or notable person. Your Wikipedia article would probably have a controversy section with a vague statement like, "Some people find crazygringo's feet objectionable."
The citation would be a podcast where a guest told the host in an offhand comment, "I went on a date with crazygringo once and thought he had oddly-shaped feet."
Any attempt to delete this statement, even by you with full knowledge of your own feet, would be reverted as 'vandalism'.
This is Wikipedia in a nutshell.
Articles for celebrities and political figures are full of this garbage, which merely 10 years ago we would consider exclusively tabloid fodder.
I've read articles on complete nobody actresses with a controversy section that listed any and every political opinion she's ever said. It's a lame attempt to extrapolate (or reimagine) someone's entire personality from a few offhand statements made once in her life.
It's low quality content like this that undermines Wikipedia. Unfortunately it's all over the site and growing by the day.
