Jin has played the role of a mother in the group since BTS debuted.

The argument

Jin is the "mother" of the group and takes care of his bandmates, and the argument treats that role, rather than any single musical achievement, as what makes him the best member. He often cooks and cleans for the other group members, and he also advises the others, serving as a good example to them. Seniority is offered as the reason the role fell to him and stayed there. Jin was born on December 4, 1992, and is the oldest member of his group, which places him in the position an older sibling occupies in any household of young people living and working together. In BTS, he sometimes does the cooking and cleaning for his members while most of the members do know how to do these things, and that detail matters to the argument: the care is a choice rather than a necessity, since the others are capable of doing it themselves. Someone who takes on work that nobody has assigned them is doing it for the group rather than for himself. The recognition comes from inside and outside the group alike. Members and fans feel that he is reliable, so they have a nickname, "mom", for him. Jin is the most pretty member of the team and he loves pink, so fans sometimes like calling him the mom of BTS, and Jungkook once called him mommy on accident on tv shows, a slip proponents read as revealing how the members actually think of him rather than how they describe him publicly. The boys know how vital Jin is for them and how Jin takes care of them. The nickname "mom" is a joke for showing people's love for Jin, and on this account the affection behind the joke is the point: he has played this role since BTS debuted, which is what makes him the best member.

Premises

Counter-arguments

Jin has said in a fan meeting that he doesn't like to be called Pink Princess or Eomma. Eomma means Mother in Korean; they call their biological mother Eomma like we say mum or mother. We should respect his opinion. We don't know BTS personally, they are people we love so we should treat them right. Streaming and voting are nice but lots of ARMYs don't have the basic respect towards them. Furthermore, he is a person with different characteristics to his personality other than simply being labeled as ‘the caregiver’ of BTS. He is so much more than that. By calling him ‘mom,’ you are reducing everything that he is to simply ‘the one that takes care of the group’. Not that that is a bad trait, but it certainly isn’t the only thing that represents Jin.

Rejecting the premises

[Rejecting P1] Caring for colleagues is a personal quality, not a musical one, and the question asks who is the best member of a music group. The premise establishes something admirable without connecting it to the comparison being made. [Rejecting P2] A nickname is evidence of affection rather than of standing, and the counter-argument on record notes that the member himself has said he does not like being called it — which makes it a poor basis for an argument advanced on his behalf. [Rejecting P3] Being valued by the group is true of every member by the same reasoning, so the premise does not distinguish this candidate from any of the seven alternatives. [Rejecting C] The counter makes the stronger objection: framing one person as the group's carer reduces him to a single trait, when the case for any member would ordinarily rest on vocal work, performance, songwriting or stage presence — none of which this argument addresses. The body's remarks on appearance and colour preference are also not reasons of the kind the question asks for.
