At the expense of coming off sounding like bunny bossy-pants: it would, I believe, be the height of irresponsibility to use a mole to echo/encourage this sort of acting-out. These words, even if nothing more than false bravado, feed similar actions, i.e. the hostage taking at the Discovery channel offices over climate change and the shooting at the FRC.
Proglodytes are emotionally weak, feel persecuted and blame others. They resent freedom for others. They are inherently dangerous.
If you have a mole that engages in such inflammatory speech -- STOP -- NOW!
It's only a matter of time before another leftist whackjob goes off. Do not be the one who encouraged him to do so when decent people will be grieving for loved ones lost.
