Generally I do agree with that statement. But I think this can be taken in a lighthearted manner. Not every joke needs to be so PC to the point where you’re afraid to say anything and all humor is lost. Humor is subjective tho so I think it’s fair to not like the joke.
I live in a hot, humid environment. Keeping bread in the fridge helps it to stay good for multiple weeks. If I leave it out, it molds way quicker. I also sometimes will store bread in the freezer to keep it fresh even longer if I know I’m just going to make toast out of it.
