ok for the shop but the base role of museum is to preserve history so futurs generations learn and we all advance as humanity. the will to hide the bad things from the past is just a will to hide history under the carpet, it’s like willing to erase history and is no different the rewriting it.
I was not answering about the article but your answer that consider showing an A6M at the entrance of a museum something bad. It’s not bad, this plane existed, it’s History.
