They're not acceptable because it's a form of abuse and disrespect. No one should subject another person, especially a family member, to such a degrading act.
A 'gay mouth harness gag' is a type of fetish gear often used in certain BDSM (Bondage, Discipline, Sadism, Masochism) or kink-related activities. However, it's important to note that these are very specialized and often part of adult - oriented or consensual alternative sexual practices. It's not a mainstream or common item in general society.
In most places, as long as it is used within the context of consensual adult sexual activities in a private setting, it is legal. However, any form of non - consensual use or use in a public place is illegal.

Sasuke could be a possible cause. If Sasuke were to go back on his word about protecting the village or if he were to harm their friends again, Naruto would be pissed. Their relationship is complex, and Sasuke's actions often have a strong impact on Naruto.
Sasuke could make Naruto pissed off if he goes back to his old ways of seeking power and revenge. Naruto has worked hard to bring Sasuke back to the right path, and if Sasuke strays again, it would surely anger Naruto.
He should first realize that a gay story is just like any other story about people's lives. He could try to understand the feelings and experiences of the gay characters in the story. Maybe he could even learn something new about love and acceptance. If he has any questions or misunderstandings, he could do some research or talk to people who are more knowledgeable about the gay community.
