The opposite is true. Privacy and anonymity are the best protection for the weak and marginalized. They are very closely correlated to the concept of free speech. And it is the ability to think and speak freely and work through matters that differentiates a civilized free society from the barbarians. Certainly, things like free speech, the right to a fair trial, privacy and anonymity also somewhat benefit "bad people". But unless you live a very boring life indeed, from time to time perhaps you will be the one who is going against the grain of society. (Or some small but significant segment thereof). And then you'll be glad that you have a safe harbor to fall back on.
