my Christian friend told me she supported pride

We’re both younger teenager. Today in her Roblox bio I saw she had a pride flag and I asked why. She responded “happy pride month :)”. I told her no, don’t celebrate that, it’s a sin. She said she just wants to support people. I told her it’s a sin just as bad as murder and all sins are equal in God’s eyes and she said she can have her own opinion. I asked her if she would support a murderer and tell them it’s okay to murder and she said no that’s different, that’s a crime. I told her both a crime in God’s eyes. She’s very sweet but has in more recent years had a quirky side like being a furry and making masks but I’m just concerned by this. What should I do?
