Future mother-in-law dissed my family's wedding tradition and I told her off. Doesn't she owe me an apology?

It is tradition in my family that the oldest girl gets an heirloom set of china that has been in my family on my mother's side for little over 100 years. I am not only the oldest girl in my family, but the only one. Now, cut to yesterday. I went by to pick FH up from his parent's house-FH is an accountant, so he was doing his parent's taxes-and FMIL mentioned the fact that I had not submitted a gift registry. I told her that FH and I would be doing a charity registry instead. FMIL did not like this-she got a funny, weird look on her face. She then said that I at least needed a new set of china for guests. I told her no, I would be inheriting heirloom china that had been in my familly for little over a hundred years. FMIL said and I quote, "Why would you want some old, stained stuff like that when you can have brand new?" She then said she would be happy to buy me new china. I was hurt and insulted. That china is pristine and not stained. I told FMIL that she was out of line, that I had never been so insulted and that "old and stained" china was priceless to me, it wasn't stained and I was grateful and proud to have it since it was in MY family and that if I had daughters, I would p it down to them, because it was a priceless part of their family history and she had no right to insult my family. FMIL shut up and didn't say a word. I left the house and waited in the car for FH. FMIL now demands an apology, yet won't admit what she said was hurtful or mean. FH told his mom she was out of line, but she keeps going on about how I "hurt" her, yet won't admit her wrong. So, do I owe her an apology?
