Good on ya, big bro, for standing up against your dad, because he frankly sounds like an abusive cunt.
If there was one thing I'd like to say to this boy, it's this: "You're a wrestler. Fuck just taking the hit for your younger brother, in this case you hit your father back, hard." But, yeah, probably not the wisest course of action.
Safer to wait until the day you move out, then slam the dickhead upside down into a vat of diesel oil.
As sickening as that was, congratulations to the kids, and shame on the father. Not just for "trying to make his son another way." But because he was threatening to use brute, moronic, violent force just to get his own way about something that doesn't matter to him.
It's one thing to spank your kids for being deliberate little shits and you feel you need to hit them to stop their behavior. It's another if you're abusing your "right" to strike children much smaller than you just because you're an asshole that wants his petty way.
Nice work, you demented ass. You make your kid ashamed of who he is and scared that his dad hates him, and round it off with a nice threat to beat him. Someone cane this motherfucker, and I hope the two brothers faced no ill consequences for this.
Yes, you absolutely should stand up to parents when they're acting like fuckheads. Good on ya. Remember that diesel oil, boys!
