Ignore her or stand up for husband

I have a half sister who I'm really not involved with. She's a religious nut and thinks everyone who doesn't believe exactly what she does is going to hell. My husband is Jewish and she believes Jews go to hell because they killed Jesus. My husband is also a bisexual jew. So you can just imagine what she thinks of my husband. I don't talk to her. She has very disgusting beliefs and I don't associate with her. My mom does but she doesn't expect me to. My husband has tictoc. I don't do tictoc but he just likes watching stuff and making people laugh. For the last month she has been commenting very homophobic and antisemitic things under my husband's tictoc. My husband blocked her twice and she made and kept making new accounts and my husband said if a women in her 30's has that much time on her hands then he's just gonna let her. It makes me angry and he usually responds to her comments as a joke. For example he visited his grandparents in Jerusalem and posted a tictoc of it and she commented that he's going to hell and he'll will burn hotter than a gas chamber. He replied with a video pretending to get in his oven. She stitched one of his tictocs and this one went way too far for me. It was a tictoc telling people they aren't alone and talking about his suicide attempt, how his brother committed suicide and his SA when he was 17. She stitched it asking why people should care about his rape when his people basically did that to Jesus. And asked if he was so traumatized by a man hurting him then why did he go on to sin and date men in college. My husband stitched herself and replied saying "Because my ex boyfriend didn't rape me? Like my relationship with him has nothing to do with what happened to me at 17"

I want to just rip her a new one. I've kept my mouth shut long enough. But my husband says he has thick skin and it doesn't bother him and he finds it comical that she's going out of her way to be so hateful. But I don't like it. This is my husband. Hate on me all you want but not my fucking husband
