I hope you realize that you can fine tune every bit of your profile to hide sensitive information (and show it to the right circles). The stalker would only be able to see that [someone] has a Google+ profile...
The goal should be that people who are being stalked, which could be anyone (and frankly will probably be me soon: I already get the occasional death threat), should be able to participate in discussions on important subjects (possibly about death threats and stalking online) /in public/ without divulging their identity. The person I responded to seems to claim that people in that situation should simply give up: that social networks are simply not an option for them. To me that is as damaging to society as claiming that people who can't see shouldn't be attempting to use a computer, as "duh: they can't see it or read anything or stuff".
