Is that threat?
PS: my dad was a Golden Gloves boxer. I learned a lot from my dad over the years. One of the things he taught me, as well as my Sensei in martial arts training was never use your skills against the weak. So no, eastus, I will decline your offer to step outside the school house.
It was intended as response to your notions of "civilized", ie "I bet you got beat up in school a lot". That such didn't immediately register on you tells most all anything they'd need to estimate the extent of your ummm..."intelligence" in an instant. But anyway....Wow!...How "impressive" indeed!...especially the bragging about your dad/etc. Had you EVER actually payed the least attention to any serious Sensei, you would know far better than to ever assume anything of an opponent. What was your school/style?...The Teletubbies Toughies? No matter. Enjoy your cherished fantasies.
OK, that was bit brusque and I mean no offense to your father, who has no fault in your foolishness here. Perhaps you're actually a serious student, and the Teletubbies bit isn't appropriate. What flagged concern is that you're most likely an inmate of one of the "Get your belts here kids!...All kinds of pretty colors to keep you paying money!..We've got 'em in white, yellow, orange, green, purple, brown and even PLAID!" "Heck!; We've got 'em in all colors of the rainbow!...even though none actually matter in any encounter!...We'll feed each and every one of you whatever "warrior" fantasies as to how "tough" you are you need to hear, just from coming here."..."We take cash, checks or plastic!" Most "schools" are of that sort within the USA. Your "never use your skills against the weak." struck me as exactly that type of crap/hype. Any serious Sensei I ever met found the "rainbow belt coalition" to be ridiculous, and believed only 2 colors were appropriate =white and black, and that some things should be obvious, as in not abusing anyone without reason.
PS: Since, as you absurdly proposed; we live in "a civilized society" and you've concern for weak opponents...I suppose traditional swords or pistols, or even thrown ping pong balls are all out of the question as well? Sigh!...This is just no fun at all
