Mr. "we don't play fair"
seethes when Aramaki "doesn't fight fair". Even though he gave alliance 7 days of rest and and number advantage by showing up solo.
Apparently Aramaki was supposed to come half dead in order for it to be fair for alliance.
Says that you are not supposed to threaten people without taking action
and yet, he only managed to threaten Aramaki without taking any action himself:
Keeps talking about how great the new gen is for accomplishing things,
yet saved them without trusting that they can handle it themselves:

Pirates don't fight fair. Aramaki is a marine. Shanks is not treating him fairly himself, and is talking shit.
He doesn't say anything about threatening people without taking action, he says it's dangerous to point guns. The implication is that you should expect the other guy to shoot too. He's not threatening without taking action, he's threatening and wishing a mf would take action to provoke him.
The "new era" that he's saving are the kids that remind him of Luffy as a kid, Momo and Toko, who obviously can't handle themselves. Luffy is the current era.
