If you think this is bad (and elements of it are, obviously), just don't look at the comments thread over at CiF.
Seriously.
The thread over on SA has a "mention Islam, get probation" rule, which sounds pretty good right about now. Seriously, some people have this bizarre inclination to go screaming "Damn right-wingers" or "Damn Muslims" or "Damn environmentalists" or "Damn anarchists" every time something like this happens, rather than "Damn sociopathic mass-murderers." Does it even matter who this guy was and why he did what he did? Does that change the nature of this tragedy?
