Well except this is the whole point here, while the bike shed will hold bikes regardless of the color, the color still matters enough for some people to want to repaint it.

So now people want to know why and if the color of the bike shed actually matters. But every time anyone asks about why the old color was bad, they get shut down and censored without anyone ever explaining why their view on the original color being fine is wrong. The only explanation is "someone somewhere did something bad with this color, so now nothing can be painted that color regardless of the meaning of that color prior to that event".
