The "results" of the reddit poll are anything but official and do not "speak for themselves". A reddit poll is not the community either and can very easily be skewed in any direction one chooses.
We are all aware of this. It has been repeatedly mentioned and acknowledged from my side. I repeatedly said I'm fine if someone comes up with an official and trustworthy way to ask the community.
Personally I don't think such an official query is needed, based on the proportion of positions in the TOO MANY threads on that topic that keeps popping up. To me it's clear that for every participant stating we should remove the rainbow there are like 10 participants showing their support for the current status. Don't you see the same?
Before my reminder post I was not paying attention whether people were talking about the pride flag before I did. So it is hard for me to answer this question. As mentioned earlier, my initial intention was to just remind that pride month is over and we should update the artwork. Only when my post got removed, and I started to get attacked, I started to get suspicious. One of the mods told me that they get "such requests" quite frequently recently and that it creates "unrest in the community" so they just remove everything related. This sounds like living in Russia or China to me. Where discussions about certain topics are just not allowed. It also hints that there are more people out there who would like to discuss it but are silenced. And when I look at the numbers of my poll before it's deletion it also hints that a big part of the community would prefer not to use those colors permanently. As mentioned I didn't pay attention to the topic earlier. But in this short time I certainly get the impression that there quite likely is a big part of the community who would like to discuss the topic but probably are afraid of the consequences or are just silenced. Believe me it is not fun to discuss this topic here when faced with the hostility I experienced the last days. And I certainly understand why many people just don't want to go into that trouble.
I guess you can see that running an official query for that topic may set a dangerous precedent.
And yet it might be the only way to find out whether your assumption is true.
