I heard someone compare walking into a crowded football stadium with being “guided to the ovens”

Last fall, while waiting to cross the street to go to Gillette Stadium for a Patriots game, there was a group of us waiting for the police to let us go. Randomly, a man said, “It’s like being guided to the ovens.” I said, “That is not funny.” He said, “Well it’s the way they are herding us together.”

I was so taken aback that someone’s first thought was herding to the ovens and to say it as a joke. It stuck with me and made me uncomfortable knowing that people think the Holocaust is humorous.
