I can agree with the shooter putting himself in the position unnecessarily.  Here in hawaii, local style = mind your own business unless you are trying to be helpful.  Mainland haole style is mind everyone else's business and make dumb comments about it, which raises the chances of a confrontation.   However, someone saying "hey you dont have a handicap placard, youre not supposed to be parking here" doesn't justify the overly escalated response.  While walking down hotel street today, a bum was saying some dumb shit to me.  Does that give me the right to shove him off the bench he was sitting on or otherwise physically assault him?

That point of view is almost like victim blaming.  Like if someone gets mugged, they shouldn't have withdrawn so much from the ATM and have a fat wallet.  Or if a girl gets raped, she shouldn't have dressed so slutty and flirted with those guys.

You just explained why stand your ground laws exist.  People should not be required to live their lives "nonconfrontationally" if they are legally allowed to do what they are doing and be where they are.

Did he instigate the confrontation?  Depends on who you want to side with. She created the situation that instigated the confrontation.  He confronted her, and then the BF intervened.  She was in the wrong, specifically because  she did not have a legal right to be where she was (handicap space).  Someone deciding to call her out on it might not be viewed as "something he needed to do or should have done," but he did nothing illegal.

Sure, we can live like deaf and dumb cattle, letting the wolves do whatever they want as long as it doesn't harm us personally.  I don't fault anyone for choosing the stand up to law breakers and bad behavior.  There may be consequences to doing that, but more often, the bullies will back down ... not bum rush you, knocking you on your tail on hard pavement/concrete.

Whether or not you agree with the self defense or Stand Your Ground claims, one thing is undeniable:

The guy who assaulted him won't do that again ... to anyone.

I’m not against stand your ground laws nor people sticking up for themselves. I just too much potential for people to “wannabe sheep” themselves being empowered by situations like this.

In this situation?  He was assaulted.

Had the BF come out and told him to leave without threats or hands-on violence, the shooter would have had the option to diffuse the situation and walk away. That's not the choice he was given.

Once you've been knocked down, the dynamics change. You are now in a situation that could get much worse for you. What you do next isn't as cut and dried as "just walk away."

Wasn’t referring to this situation.

And I meant “wannabe wolf” type of sheep. Just think this isn’t too far from SJW type BS.

Again, not disagreeing with you. You’re right. So 

An assistant men's basketball coach at Wake Forest University has been arrested and charged with
assault in connection with a deadly attack on a tourist in the New York City borough of Queens, police
said Thursday.

Investigators say Jamill Jones, 35, punched Sandor Szabo, also 35, in the head following a confrontation
early Sunday. Szabo fell and hit his head on the pavement, knocking him unconscious. He was rushed

In Florida, a first-degree murder conviction can require that the state proves a homicide was premeditated, while in a second-degree murder case, they must prove the defendant acted with a "depraved mind."

Rickman said second-degree murder can be classified as "heat of passion" crimes. While the people involved didn't have to know one another, the prosecution must show the aggressor harbored ill will or hatred or some type of evil intent — descriptions that speak to one's state of mind.

In a manslaughter case, prosecutors wouldn't even have to prove Drejka acted out of premeditation or a "depraved mind."
