Fair enough. But I think we just need to stop sharing false information about how much better clipless are, because they really aren't. I think it's crazy when I hear new touring cyclists get told they need clipless shoes. No one needs clipless shoes.
How much better clipless pedals are is relative to how hard one chooses to ride. The more effort you put out, the greater to advantage is. I don't believe this to be "false information" at all.
I switched from toe clips and straps to clipless pedals (for both mountain and road bike) in about 1987 and I have no regrets whatsoever. I do use flats on my beach cruiser for riding down to the corner for a slice of pizza though.
But like I've said, I have no problems with those who prefer to use flat pedals, or any other gear choice that they feel is right for them. Freedom of choice!
