Her post was speaking on what someone should do if they're going to throw hands. She isn't wrong.
The "video on the internet" shows the consequences of taking half measures when you're engaged in a physical altercation.
You're placing too much trust in someone who is going to feel embittered about getting their ass whooped.
Try your best to walk away and diffuse the situation. If you're in a fight, you cannot afford to hold on setiments.
ok say me and you want to fight. take me through the scenario
first of all you would have to have the power and stamina to take me down. then you're going to need to be able to turn on a kill switch and take it further.
now you're standing there for 3 minutes beating someone's head in hoping they dont get up. because "they might have a knife"
and you think this is normal, ok and possible?
you think the other person wont then try to kill you in the same fight?
you dont think that makes the justification to shoot first even better?
you think you wont go to prison?
you think the even more embarrassed person still wont shoot you later?
the amount of time and effort that would go into to beating someone to death can be funneled elsewhere.
it is not easy to kill someone with your bare hands, that is a conscious choice.
