I'm posting with my real first name at least...
at first I thought you are joking now I am ???
I don't know about you but I have dozens of emails, my "real" one is the one for people I take seriously and close friends.
I only have a couple of email addresses. I'm not worried about someone knowing my email address... Why would I be? I comport myself online the exact same way I would face-to-face. If anyone is sending me annoying/abusive emails I can simply block them. But that has never happened...
