Reality is that it would drastically reduce comment trolling, if your real identify was viewable and searchable by all you know. That is not at all clear, especially as a percentage of comments. There are plenty of sociopaths who are perfectly willing to troll under their real name. Meanwhile, more reasonable people may quite rationally be worried that expressing any opinion on a controversial issue will lead to online mobs trying to get them fired from their jobs, kicked out of school, or otherwise ostracized. Not to mention scenarios like being a gay teenager in a very socially conservative environment.
