Currently downvoted but very valid point, ref the Sherlock tool posted the other day: it is not hard for me to imagine more bad uses for it than good, but that alone shouldn't make it illegal.
On the contrary, I wish more people would. But sometimes people take authentic self to mean something like purely individual expression, without regard for the commons or the needs of others. I don't think that can be right.
Most times when commenters here break the site guidelines, it doesn't feel like they're expressing their authentic self at all, but rather that they're avoiding doing that by attacking someone or something. If they would simply share their actual experience, it would be fine. But that's not so easy for most of us.
Most oppositional behaviors are just inversions of conformist behaviors—the same thing, with one bit flipped. Whatever authentic means, that can't be it.
