Oh I like the argument about, what you dont know cant hurt you. I'm not sure I agree with it though. I grew up being lied to, and I didnt like it. Humans "work" better ie can be happier? if they can trust someone.

Just for the sake of argument, my first marriage was monogamous, the 2nd was not, and the 2nd was to some degree better than the first, but ultimately both sucked. The deciding factor was not faithfulness at all.
