My feeling is that what we say here, although it could be used against us in the media, is far different than actually appearing at an event like the Wellstone funeral and acting disrespectfully.
Venting. Yes, there is something to that...but I was making a larger point: that we simply don't need that level of hate/vitriol.
An opponent has paid his respects to one of our fallen. Mentally and emotionally, we should simply leave it at that (though the cameraman's trespass is outside the scope of that point).
