Well, the comment I was responding to is about technology eroding the "self". We agree that sharing and expressing one's ideas make them stronger, allow them to blossom and mature, yes? Maybe you have this crazy idea that's too out of the Overton Window to discuss IRL and attach to your public image right now, but there are other people thinking about it somewhere, and if these people manage to find each other online and discuss it they'll be able to reflect about that idea rationally, without fear of judgment and repercussion.
That's how novel artistic and political movements are born, from people not being afraid to share "offensive" ideas. "Secret online alter egos" allow you to discuss ideas that you couldn't have considered otherwise, and because we humans tend to restrict our thoughts to our field of possibilities, these alternate identities will actually make you have more of these creative ideas.
Of course you can keep all that to yourself and either continue living the life that society has prepared for you, or try alone to change it, but that's pretty limiting.
