I don't think its fair to label her a homophobe. The black hair girl clearly loves the orange hair girl like a sister, cares about how she feels, treats her very well, trusts her a lot. And orange hair girl is just abusing that by layering affection on her like its going to change her orientation. Its a flat out betrayal of the trust black her girl gives her and an abuse of the part of her self and her emotions that she left in the care of someone she thought was a sister to her. This is traumatic and extremely stressful, especially when it keeps occurring, when orange hair girl keeps pushing. Black hair girl's reaction in this situation is a perfectly normal reaction to the amount of stress she's been under trying to reconcile the feelings of betrayal and love conflicting within her, and that's before we even consider the fact that she's an immature 16yo girl that's scared she's losing her best friend just because she can't love her that way. Is it not normal to be severely discomfited in this situation? Maybe she's been developing into a homophobe because of the way she's being treated? Its totally unfair to her to expect her to be able to handle this maturely and with grace and especially cruel to turn on her after you've done the damage, talking about her behind her back like she's some unreasonable bigot when she hasn't even had a proper conversation with her, just unloading all her problems on her like she's obligated to be there for her, blaming everything that's gone wrong on some warped sense of righteousness that states you must be correct because you're gay. Black hair needs help, she needs a friend, and instead she's getting a knife in her back when she's at her lowest.
