If he's a news broadcaster, then by all means, be as impartial as you like. But, he's a commentator, and someone who has written and spoken at length on injustices around the world, and most especially in his own country and America when it comes to the subjugation and historic plunder of black people, where he well and truly spoke truth to power.
If he can do it there, he should have done it here. He knows full well, the parallels of the experiences between the two causes, and he also knows full well how close the two movements are ideologically.
Also, vitriolic?
If speaking out against the senseless murder of children is vitriolic, then call me vitriolic. That would be a badge of honour for me.
Though, it seems you like to make false equivalences between a besieged population and an nuclear armed, occupying force who is bombing said besieged region to kingdom come. So, maybe I shouldn't be surprised at your response.
