Learn English – Word for when something wrong is made to seem normal because it is common

single-word-requestsword-choice

Someone made this statement:

You found the perfect partner (looks, finance, personality) but the
sex is a bust, would you cheat?

I found it offensive that she was making the question 'would you cheat' look very normal but I didn't really know how to describe it. I pointed it out but she claimed there was no need to brush such a present day reality under the carpet. I considered it logically and eventually used the term Argumentum ad populum to express the fallacy in her statement but what I actually wanted was a word to use in describing her action i.e. making something wrong appear normal because it is common. I couldn't come up with anything, any help?
