There's a large enough class of people that would tone down what they say if they were tagged about what they say ( what if I could link you back to some posts on Stormfront?), or if the person they were wishing to die had a name.
At least with pro username websites, you can opt into real names. I feel like this is the optimum approach, and that all others are subversive to a completely free conversation, which is what the internet first championed.
No fake G+ profile required, and each G+ Page identity is actually tied to its own auto-generated Gmail account, not the host Gmail account.
So they actually actively support your use case, its presence has just been drowned out in the commentary.
1. You mix pseudonym and anonymous (your other post says "They do officially support anonymity").
2. The Real Name™ BS is still binding for the main G+ account. I have to tell Google my name, then they are kind enough to allow me to enrich their knowledge about me with all the online handles I use...
That _might_ be enough for the use case the GP described, it very much isn't 'anonymous', not 'pseudonymous' if you tell name and handle to the biggest ad company on this planet and still a real name policy that is utterly broken and stupid.
(Minor G+ rant follows)
People like me are seeing the technical proficiency of the G+ system every day. If my GMail tab (for whatever reasons) logs me out I can log in again - just to be sent to my 'suspended profile'. Note that I was looking at GMail moments ago and certainly would like to see Gmail again.
Instead of G+ I get this:
Your profile is currently suspended
Until your profile is unsuspended, you will be unable to use this feature.
Visit your profile to learn more.
As for the rant, random brokenness/inadequate customer support is hardly a trait limited to G+, it extends to all their products.
Honestly, the chilling effect worries me. I appreciate that a lot of people would rather just not deal with the like of Stormfront, and simply pretend to themselves that people like that do not exist, and that those views are not held, but this is a harmful way of dealing with anti-social views.
Even if we argue that a real-name policy would totally kill off all hateful comments, we have to consider if this is even a good thing; hateful comments should be met with rational arguments that undermine them, and show them to be incorrect. If someone says "all [people of some class] are evil", then one solution is to shame them into shutting up by linking their comment to their real name, but this just allows them to continue to think this way without ever hearing a dissenting opinion (I mean, they're hardly likely to bring this up in public, are they?).
The internet has a wonderful power to throw people of contrasting views together, and get them to show each other how they think, and allow them to change their minds. The mere fact that this process may sometimes result in offense isn't a good enough reason to stop it. If someone's views offend you, then it is your duty to prove them wrong and -- if you cannot do so -- consider that your own views might be incorrect.
I know I've personally debated with others online and learned from the experience, and I also know that I'd never have done so were it the case that I would have had my real name linked to the views I was espousing. It strikes me as incredibly harmful for society in general to attempt to silence offensive speech, not only because it means that those who hold offensive opinions can never be proven wrong, but also because it means that unpopular, yet true, opinions have no platform to be proven right.
If say I am watching a clip on guns, and then I make a comment on the clip, against or for, people will realize I watch clips on guns which I'd rather not share.
5 out of 7 times I've tried to create a Google accounts over the last years I was asked for a mobile number (that an SMS was to be sent to) before I could register. Given that a huge chunk of android users synchronizes their address books with google my mobile number is effectively as good as my ID.
Unfortunately those 3 times I actually needed the account I was trying to create all required my phone number, so they are all tied to my real name (and address and birthday, etc.).
