Boring answer but…
>>832047>I find the question/premise faulty>win any street fightBullshit premise, most men are disposable so it's best to avoid problems. You get injured, you get incelled so don't be a hero because you're not owed shit.
>I would choose to confront the guy directly about his behaviorThe guy is entertaining ideas with this girl and that should be nipped in the bud. I would make a joke or two about it in front of the group to alert everyone. If he's aggressive, you don't need to confront him directly.
There needs to be fewer men than women by 30% in the population and they need to be raised better and with better prospects. Leaving them to be raised by the market and dating courses is bs. Some men get raised to be aggressive or get lucky a few times being aggressive and then think it's ok towards women in general.
