homophobic friend

Hello everyone, I’m 16 years old and in high school and I’m in a friend group of 6 girls including me. Lately my friend has made a lot of homophobic comments although I think that she doesn‘t realise that she‘s homophobic. Here are some examples:
„I‘m not a fan of seeing two men or two women kiss“
we were talking about the csd and she asked if anyone was going there in like a sarcastic way and said „I‘m not really a fan of it“ then we talked about it again and she said „who even goes there?“
Another friend pointed out a flag pole with an lgbtq flag at our school and we were all shocked bc we didn‘t even know that there was a flag pole at our school but she seemed to not be shocked by the pole but rather the flag and then again said that she isn‘t a fan of it but isn‘t completely against it.
And obviously this is not okay and since this has only been happening lately I‘m also very shocked. But somehow in these situations I‘m in such a shock that I cannot confront her about it I‘m not sure why even though I‘ve planned to say something. And I feel really bad because I don‘t want to be friend with someone homophobic but I also don’t want to cause drama. Because even if I confront her she isn‘t going to change her way of thinking and she is just going to say that she isn‘t homophobic because she doesn‘t directly insult gay people and because „she isn‘t completely against it“. Also I can‘t just stop being friend with her bc she is apart of our friendgroup and I can‘t change that. In this friendgroup I know that atleast 1 girl wants to say something aswell, another girl also thinks it’s weird that she says all those things and another that definitely isn‘t homophobic but doesn’t seem to care about the comments (not sure about the last girl I‘m not close to her maybe she also finds the comments weird). And the last girl I‘m not sure about her because in the past I‘ve seen that she liked videos against trans people and me and my friend also confronted her about it but she hasn‘t said or liked anything in the past year (considering what I know about her she gets influenced quite easily and often takes the opinion of the person she is talking to and in general she changes her opinion often).
What should I do?
