We've got artists, scientists, scholars, pranksters, publishers, songwriters, and political activists.  We've subjected Discordia to scrutiny, torn it apart, and put it back together. We've written songs about it, we've got a stack of essays, and, to refer back to your quote above, we criticize the hell out of each other.

More nerd points for anyone who can solve this (it's not a hw problem of mine; I'm far too advanced *gazes at self in mirror*)
For a topological space X,
X is Hausdorff iff the diagonal (the set {(x,x) | x in X}) is closed in (X, X)


Hint: look it up on google.
Hint for those inclined to do work and not be compensated: Limit points! (I seem to like limit points)
