I Have Nothing to Hide Question

I believe that we should all be concerned with privacy and the internet. There are many reasons for this; one of the main ones is that most people use the internet for several different reasons. I know that I have bought several things online and have given websites my credit card information to do this, I am sure that many other people have done the same thing. By people saying they have nothing to hide on the internet then they are saying they don' t care if other people have their credit card information. Another privacy concern I have is the internet knowing too much personal information, like where we live and where we are. This poses a concern because people could use the information in a harmful way.
