I know. I guess I just felt like ranting a little. It was just annoying to hear him say that what Sakura says is irrelevant. He doesn't even bother to think that it might have meaning. But you're right, he is bias so I shouldn't act as if this was unexpected.
My bad.

And what does Hinata's relevance extend to when it comes to the general plot? I doubt this Sawyer individual has failed to consider just how little Hinata's character has provided except for recent events. Let's list her accomplishments since the beginning, shall we?
Hinata's Contributions1. Apologized for Kiba before an argument could intensify between him and Naruto
2. Offered Naruto the option of mimicking her test answers which he refused
3. Performed reconnaissance duty that allowed Team 8 to locate Gaara's group and approach them which almost cost them their lives
4. Provided medicine to Naruto after he finished fighting Kiba which was of questionable value since his recovery speed is already greatly increased thanks to Kurama. It's a kind gesture nonetheless.
5. Provided Naruto with some emotional support when he was uncertain about his upcoming fight with Neji
6. Offered reconnaissance duty once again during the Itachi Pursuit arc that allowed the group to follow Tobi's movements and then later extinguish some Amaterasu burning flames whilst the group reached the Uchiha hideout ruins after Sasuke had already been taken away by Tobi
7. Attempted to protect Naruto from Pain when he was incapacitated. Instead of doing something practical like attempt to remove the stakes which might have actually helped she just decides to charge Pain in a futile attack after she gives her declaration of love. Of course she's promptly dealt with by a single ST but that's not before Naruto lost all sense of reasoning and transformed into 6 tailed Kurama. Whilst her actions may have indirectly saved Naruto's life had it not been for Minato's convenient storage of chakra in Naruto which was able to suppress Kurama after having been released then Konoha might have ceased to exist and we'd have the 9 tailed beast ravaging through the Land of Fire.
8. Fought alongside Neji against some Zetsu clones
9. Protected Naruto from Mokuton stakes
10. Perhaps her biggest contribution is the motivational speech she gave to Naruto which allowed him to pull himself up from the depths of despair. I'll give her credit for this because it's a major event albeit it's an overused concept since we already saw this happen during the Invasion of Pain arc.
11. Put Naruto's shoulder back into place

Honestly, her relevance was at its peak during 614-617 but really in comparison to Sakura when you consider the entirety of the manga and not just the recent chapters Hinata is an irrelevant character. Sakura was saving Naruto's life back during the Land of Waves arc and even though Kishi really seems to be doing his best at downplaying the heroine in some of the recent chapters she's still had more plot significance than any other female except maybe Tsunade.
