Well, "you just looking at me" can't be selectively edited to remove appropriate context and uploaded to YouTube before I even get home that night, to live on forever searchable under my real name, should you decide to post that too.
Say I speak up with a well-reasoned opinion about Arizona's recently tanked gay discrimination bill (or "religious liberty" bill if you are on the other side of the fence, not that I'm drawing a moral equivalent). You remove all the well-reasoned beginning and end parts and only post the middle part where at some point I'm characterizing the crazies by saying "gays will give regular people filthy gay cooties by sitting at the same lunch counters". You get this onto Upworthy with headline "[My Location] [My Job Description] [My Name] Has Unbelievably Ignorant Opinions on Gays". There go my employment prospects in San Francisco, er I mean, [My Location].
If it's in your memory, you can quote me out of context while talking to others, at worst. I might even be able to defend myself. If you edit and post to YouTube, no such remedy.
