"Isn’t this inciting violence?"
Taken literally[i then yes.
But people [i]don't] take it literally, do they? Any more than Kathy Griffin holding up the "severed head" of Donald Trump in her "comedy" show. Or the rep company which played Julius Caesar in modern dress Central Park with the assassinated Caesar being played by a Trump look-alike.
These things are bad taste, but not to a believer in free speech like me a matter for the law. Naturally in today's America if the severed head was that of Obama, and the Central Park Caesar looked like him, both Ms Griffin and the producers of the play would now be in prison.
Similar recent case of the double standards by which hypocrites on AB and elsewhere in the UK live: Youtube conservative Carl Benjamin jokes that he would not rape Jess Phillips and is set upon by all the media mouths like Victoria Derbyshire (and people who should know better like the moral busted flush which is Jacob Rees-Mogg) for "incitement to rape". Ms Phillips, who eats six inch steel nails with her cornflakes, says of the thousand plus women molested, stolen from, intimidated and, in a number of cases, actually raped in Cologne New Year's Eve 2014 compares those gross crimes to "a normal Friday night in Broad Street Birmingham". That is a genuine case of the trivialisation of rape, but one of AB's hypocrites will call her oout on it, will they?
