I'm pro-privacy and I still think these retorts just make it sound like you've put zero effort into understanding what the "nothing to hide" people are trying to articulate.

E.g. "Can we put a camera in your bathroom?"

Very few people are arguing that nudity or bathroom use shouldn't be private, and they are not going to understand what this has to do with their argument that the NSA should be allowed to see Google searches to fight terrorism or whatever.

Privacy arguments are about who should have access to what information. For example, I'm fine with Google seeing my Google searches, but not the government monitoring them.
