How sad and upsetting. Whoever said, "fly free, baby girl," in a tweat seems almost reckless, like they're romanticizing suicide. I guess they believe you can throw this life away and have another one in clouds, but that is almost certainly a lie. Suicide is a grave mistake. Death is absolute and final. It's a murder, and while the killer is also the victim, the act of suicide for attention is misguided and evil in and of itself. Martyrs are trying to emotionally blackmail people, but unless you're Jesus Christ himself it isn't worth it.
Society might be improving for LGBT people, but in cases of suicide most people will only gasp in horror, maybe decry the injustice and then move on. Clearly, the parents did a terrible job of supporting their child. They let their child believe that she couldn't be herself without humiliating them. Someone needed to tell that kid that it doesn't matter whether other people judge you or hug you, your life is your most precious thing and it's not for anyone to throw away. Instead, they relied on a fake God and an evil religion, and this is the result of their inhumanity.
