Two sides of the same coin:
"I want anonymity because I don't want to be a victim."
"I want no anonymity because I don't want to be a victim."
Most people don't want not to be accountable; they want to protect THEIR daughters and sons.
There was a fascinating classic old SF story called First Contact by Murray Leinster, expressing a similar dilemma - the desire to trust, but unwillingness to risk being the first one to do so. It was written at a time when society was also going through a period of being forced to deal closely with anonymous strangers, both at home and abroad - 1945.
