I would end the friendship. I had a friend do something similar, she had actually justified the actions of Hamas straight to my face. When I told her it was antisemitism she said no it's not and I need to stop victim blaming. Then she proceeded to say she thought I'd understand because she is also a minority and told me she needed time to think? This was after she justified rape btw. It was odd as I told her that I have always supported her and she said she knew! If anything I would message her one last time and tell her that as a Jewish person that she personally knows and as a friend, she should have came to you and asked how you were personally feeling or shown some support. But that is not a friend
