This I think is something we have to put in the front of our minds when we're discussing these husbandry practices. I see this a lot on the aquarium forums, and I know fish and reptiles aren't the same, but they are in the sense that there are established care guidelines for certain species that cannot be kept in groups. A very advanced keeper will say something to the effect of "it works for me" or "I've been keeping X for 20+ years and never had an issue" etc etc, and new keepers with no experience assume it's okay, and end up with dead/injured/sick animals.
I don't think there's anything wrong with discussing alternative husbandry practices, I would just ask that the more experienced of us try to remember our audience.
I encourage you to safely experiment with different things, and then bring your findings here to discuss, but you can't be mad when people have counter arguments on why what you're doing may not be right. As an example, the thread we had awhile back about the big breeder's feeding method. That gentleman tried something new, presented his findings, and we as a community determined that we wouldn't be recommending that method to anyone based on scientific and established facts.
Much like that scenario, the benefit of keeping multiple BPs together is for you the keeper not for the animals, and I think you'll find most people here advocate for the wellbeing and safety of the animal above the desires of the keeper.
Respectfully, claiming that we all have fixed thinking, and then citing Copernicus and Galileo as the reason we're all wrong comes off as a little pretentious.
