CMV: I think it’s wrong to hit someone for what they said no matter how bad it is

I’ve seen multiple examples of people saying some really mean things to someone else and when the person retaliates and punches that person, people are typically on the side of the person who punched the mean guy. For example, there was a reporter who was trying to tell Buzz Aldrin that he hadn’t gone to the moon so Buzz punched him and everyone I’ve talked to and in the reddit comments seem to think that it was justified. There are also many examples in movies where the good guy will be sitting at a bar and a group of bullies will come over and start making fun of him and when the good guy gets offended he fights them and beats them up. I just don’t think that there is any combination of words that would justify causing physical pain to someone else.

Edit:  I'm saying if there is nothing related to physical pain that they said then I don't think they deserve physical pain against them. So threats to do not count in relation to my post.

Here's the thing.  In the cases that are celebrated, the bully is counting on the fact that the other person will sit there and take it.  They are subjecting their target to harassment because they think the target is powerless to stop them.

In the Aldrin video, Buzz tried to get away, but the jerk stayed in his face.  

It's not "right" to hit them, perhaps, but it's more right than sitting there and being taunted by someone who believes you won't take action.

Why it's celebrated, is that we've all been in situations where we had to suck it up and be humiliated because of a power imbalance.  Take the stereotypical incompetent boss who knows he can't get fired because he's the owner's son, who berates his vastly more qualified peers.  But when the bully doesn't realize that the owner just lost his fortune and the new owner loves the target who wouldn't love to see he bully humiliated.

We like to see the underdog turn the tables on a bully - this is just another example of it.
