Is this a red flag?

So a few days back, I was talking to a friend of mine.

We were having some funny banter in which he crossed a line, which made me angry.

He made a sarcastic remark about my dad.

So, after a day or two, I opened up and told him that I didn't like what he said.

I am giving you five major points now.

1. First day, he said he is sorry but I should be ready to take jokes when we are joking.
2. Since I don't like such things as a joke even, I was not behaving naturally.
3. Cut to day number 5, he said, It's an unconditional apology and disconnected the call right after that. No chats no talks.
4. Later that day, he admitted, if I would have said anything like that for his father, he would have stopped talking to me.
5. On the same call, he said, I have not said anything which is such a big deal.

Am I just making a fuss about a small thing?
