This is a bad use of I don't care. Can you give me some good ones?

"You may have given me a list of irrefutable problems with Kingdom Hearts which proves it is a bad franchise, but I don't care. I still think it is a good franchise."

Me: My guy, if you truly don't care, you'd simply keep this stubbornness toward that irrefutable list of mine to yourself instead of posting that as a reply toward this comment. What are you trying to achieve with this comment if not for farming likes from blind fanboys and to feel better about yourself?

I see no fallacies here. I assume "Kingdom Hearts" is some form of entertainment in which case there needs to be no logical or rational basis for one liking it. They could just like it (affective/emotional).

I would say that your reply might be a little overly-abrasive given the content, but I don't know the history and being a little overly-abrasive is not fallacious either.

This just seems like a typical internet flame war.

The use of 'I don't care' seems okay, given we know that the other party is saying here - they 'don't care' in the sense that your 'irrefutable list' doesn't change their like for the game. So it's not necessarily true that if they 'didn't care', they wouldn't reply.
