Dafuq you talking about?
I am saying Shanks can't go jibbly wibbly going after a Yonko in his own territory.
And when BB wasn't in Hachinosu, that executive told Shanks they didn't know where he was.
Shanks said he went to Wano because he thought Teach would appear there.
Most likely, Teach is the pirate Shanks mentioned to the Gorosei. Shanks has every intention of trying to stop Teach.
You're a trying to find a weird ass "perfect scenario" that, if Shanks can't go against Teach anytime anywhere, than he can't go at all.
Mind you, that I ain't even trying to "shit on" Teach or anything. Is just that your arguments about Shanks "not wanting to fight Teach" make absolutely no sense at all when the manga has show clear signs that Shanks has intention of trying to stop Teach.
