Could be. To me, the story goes as follows:
-OP has a conversation with their "friend"
-Said friend brings up a ceratin (otherwise tame and non-controversial) website, expressing her dislike for it
-OP has a different opinion, so asks her to elaborate
-"Friend" gets triggered and insults OP
Unless you are white knighting because the "friend" in quesstion happens to be female, or you have been succesfully gaslighted for years, it should be clear that for this "friend", OP was never a real friend. They were merely a utility of reassurance and emotional comfort to her. OP made the unthinkable mistake of having (and expressing) a different opinion, so they had to be taught a lesson.
If you think that this was all OP's fault, and it is perfectly fine to throw a fit and insult a supposed friend over an AI, then I don't know what to say.
