So it's being a while that Shankstards, or at least I believe it is them but could be any other tard, have being claim Shanks as Tenryuubito and the reason why Gorosei accepted a meeting with him. Like he having a pass to do whatever he wants because of it.
First of all that claim should have being already debunked when Doflamingo backstory came up. Doflaming a proved Tenryuubito didn't had any special treatments of WG. There is the narrative of he using CP-0 for his personal purpose but at the end he was treated like any pirate once defeated and all his crimes revealed at Dressrosa. He was arrested and took to Impel Down. So it doesn't matter if you are Tenryuubito or if you know Tenryuubitos secret etc. He was just a pirate at the end.
And same thing with Shanks. In fact this last chapter 1086 we just had another proof of it.
Even a Tenryuubito that doesn't make a living as pirate was killed by the simple fact of backing up Fishmen. Imagine what they would do with Shanks if they could (that means if he wasn't a freakingly strong Yonko) that stole the Nika DF they were so concerned about it.
Well that's it. Shanks didn't met Gorosei because he is a Tenryuubito. He can be a Tenryuubito. But Doflamingo isn't meeting with Gorosei and he is confirmed to be one. Shanks met with Gorosei because of his positon as Yonko.
