Ditto - using your whole real name invites problems for some.
Many times it isn't about convictions or anything but simply a nickname used in familiar company. Or a nickname given to you in flight school (Pugs). Or you may be a fan of a particular brand or product. I worry less bout a dudes name than I do about anything else.
As to handles here vs elsewhere - I would say that here is less than others.
Notably AR.
I seriously doubt that if someone tosses an insult they do it because they "feel safe" behind a fake name - they do it to toss the insult and not to do a "drive by" posting.
