This means I can stand on my property, shout all sort of expletives to entice someone to trespass -- so I can shoot them then. Seeing that you believe any level of instigation - as long as I am on my own property gives me carte blanche to shoot whoever I please. Under your definition I can probably throw shiat at them and still not be considered the instigator if I'm on my own property.
Technically the trespasser would be instigating because he is trespassing.
In cases where there is no clear instigator like Zimmerman and Travis the defendant can claim self defense in let the jury decide.At least it would stop people like Travis and Zimmerman from getting away with murder with the steps you described.
