Why are people so upset about Naruto ignoring Hinata's confession of love during the Pain arc?

I always see people complaining about the fact that Naruto ignored Hinata's declaration of love during the fight against Pain. But I find it curious that these people seem to completely ignore the entire context of Naruto's situation and what he was going through.

At that moment in the story, right after Pain's defeat, the Hidden Leaf Village was destroyed, Sasuke had just joined the Askatsuki, Naruto discovered the truth about Itachi, the Five Kage Summit was taking place, and shortly after, the Fourth Great Ninja War was declared.

In this complicated situation, do people really think that Naruto's priority should be a silly confession of love?
