Most people would assume that a husband would OBJECT to his wife being a stripper. They would assume that this man is one of the majority of men who would not like it.
Therefore, if the husband says that it's no problem, their first instinct would be to doubt him, to think that he is lying.
However, if you accept that there are many types of people on the planet - those who DO object to their wife being a stripper being the majority, but a few who don't object at all sprinkled in, then maybe he wasn't lying.
There is no assumption at all that there are "a lot" who feel that way - to the contrary, there is the assumption that there are very few - but those few are one of the "all types of people" that make the world complete.
Okay, another example. I love chocolate. I assume everyone loves chocolate. I offer you chocolate. You say you don't care for it. I am stunned, I think you are lying, I think you are rejecting my offer of friendship that was given in the form of offering you this chocolate. Then I stop and think "Well, maybe there are one or two people on the face of this planet who don't like chocolate. After all, it takes all types to make the world complete. Weirdo."
