The inconvenience of having to undress would annoy me, as do having to take off my shoes and put my luggage through a machine.

I would only be annoyed for reasons other than inconvenience if the contact is unprofessional. Assuming that it's not, and everyone else is doing the same, I wouldn't feel like I was being violated.

My basic point is that the liberty being infringed upon by these scanners (i.e. liberty to hide your genitals from people) is frivolous. So I'm asking for other reasons that these should be disallowed. This seems to be a very unpopular point of view for some reason.
