It is a redundant descriptive, I'll grant you since violent and leftist now mean exactly the same thing. Had I stipulated violent leftist nutter then that also would have been redundant.
WHAT IS PROBABLY ANOTHER VIOLET LEFTIST NUTTER SNIPER JUST SHOT TWO PEOPLE AT A TEXAS ICE FACILITY. BUT I AM SURE THAT LEFTISTS WILL CLAIM THAT THE DEAD ASSASSIN IS A TRUMP-LOVING CONSERVATIVE.
