Am I wrong in this situation?

We are a family of Coptic Christians me(55M), my wife(54F), our son(25M) and our daughter(24F). Our family was kicked out of Egypt in the 80s due to Islamist violence in which my parents and many of my extended family members were killed, and we had to move to the US as refugees. We had to start from scratch, and it was difficult initially. I had to do double jobs to get some stability with which we were able to educate our children. My son got a decent job now, and we are doing great in the present day.

Two years ago, our daughter announced that she intends to marry a Muslim man. I straight out refused and told her although she is legally free to do as she's pleases, I will never accept her marriage.

Our family doesn't have any problem with interfaith marriages as long as they are with liberal people. One of my cousin's is married to a Jewish lady, while another is married to a Catholic man. However, we never allow marriage with Muslim families unless the opposing families are liberal. Most Muslim families encourage their sons to date non-Muslim women while kill their daughters for dating non-Muslim men. The reason they allow their sons to do so is to convert he woman to Islam and raise their kids as Muslim. My daughter's husband comes from a conservative Muslim family, where most women are not even allowed to step out of their homes for things other thane groceries. They are also huge supporters of Muslim brotherhood, an Islamist terrorist organization which was responsible for the killings of many of extended family members. This is the primary reason for me not supporting her marriage.

I tried to reason with her with all this, as well as the fact the his family is ultraconservative, but she said we are racists and Islamophobic. I asked her if she things it's fair for my family to get killed by the group her husband's family supports, she told me that they probably deserved it. My daughter subsequently told us she finally had enough of us and this will be the last time she speaks to us if we do not accept her marriage. This was enough for me and I finally told her I promise this is the last conversation between us, and she is dead to us from today. My wife told her if abortion was readily available during her time, she'd have preferred to use it. Our extended family soon followed suit and everyone blocked her. We soon did a symbolic funeral in her name, to solidify her being dead to us.

2 years later, she tried to reach us. We gave her a past invitation of her mock funeral and told her to never contact us again. She tried again, which we considered as harassment, and reported to the authorities and got a restraining order on her. She tried to go to our son's workplace parking lot, where he had to call security to get her physically removed.

We were subsequently informed by a doctor that she suffered sever physical abuse over the last two years. Her husband had married another woman without divorcing her, and kicked her out last month. I was thinking of forgiving her, but my wife said she'll leave me if I spoke to her again. Last week, she was in critical condition and told us she wanted to meet us one time. On our arrival, she started berating us and told us if we had accepted her marriage, she'd have a support system. . She told her everything she suffered was our fault. Her brother told her she did not deserve our support and she is a disgrace on our family who died for us to two years ago. My wife told her angrily she hope she burns in hell and to die already. I subsequently decided it was time to leave and left her to fend for herself.

But still, I wonder if I am wrong to cut off my daughter for marrying an Islamist? On one hand, we could have saved her from physical abuse if we did not cut her off. On the other hand, she still refuses to take responsibility, and blames us instead of her Islamist husband.
