There are many, many other videos on Youtube and elsewhere that show him telling his audiences to "knock people out" and that protesters used to get "put on stretchers" back in the 1950s and 1960s. I will never forget the North Carolina incident where to young black men were leaving one of his rallies and an old white man elbowed one of them in the face and was charged and convicted of felony assault. The president on many occasions called for violence.
You are not distinguishing between INSTIGATING violence and RETALIATING against violence.
In the 2015/2016 campaigns, peope were instigating violence - many often PAID to instigate violence. By far most of the violence was instigated by the left. I'm sure that there was some of this on the right as well, but nothing like on the left. What Trump was referring to is RETALIATING against the instigators.
If someone comes lunging at you with a club, one has the choice of either flight or fight (or get beaten up). Trump chooses to fight. I can't recall Trump ever calling upon anyone to INSTIGATE violence.
