@CheeseMmmm Saying it's too young to think about sexuality is homophobic.. Sorry that's the bottom line.
Maybe if you'd actually read people's posts instead of spamming the thread with long posts filled with song lyrics you'd stop being so obtuse. The problem is that children are being socially groomed to think that being inclusive in their sexuality is a good, kind thing to be. That's not even remotely similar to a child being aware of their sexuality at a young age.
Your own sexuality is a private thing and being heterosexual, homosexual or bisexual (the only three sexualities) doesn't make you a better or worse person. It doesn't make you kinder to be open to having sex with everyone. It doesn't make you boring to be straight. It doesn't make you bigoted to be a lesbian or a bisexual. But that's what children are growing up with now, especially girls. Girls who are exclusively same sex attracted are considered to be TERFs for not including transgirls in their sexuality. Girls who consider themselves to be bisexual are bigots for only recognising two sexes. Even if they are attracted to a transgirl, it's not ok if any of that attraction comes from the fact that they are also attracted to male bodies. But girls who rise above all that and are willing to declare themselves attracted to every kind of person are the gold star. Good, kind girls who will accept and include everyone in their sexuality. It's not even remotely homophobic to want to protect children from the idea that their sexuality is anything other than deeply personal. That they will never, ever owe anyone access to their bodies. That they should never be pressured into accepting anyone they aren't actually attracted to.
On the other hand it's 100% homophobic to try and convince children that being exclusively same sex attracted is unkind. That their sexuality not including transwomen or transmen is a bad thing. That they are hung up on 'genital preference' and should get over it.
And lastly, while it's not unusual for an 11 year old to be aware of their heterosexuality or their homosexuality. It actually isn't particularly usual for an 11 year old to be totally aware of their bisexuality at that age because being fully aware of an ability to be sexually attracted to people of both sexes usually takes longer and involves a greater degree of sexual maturity. In fact, it's not unusual for people to be in their 20s, 30s, 40s, 50s, or older before becoming aware that they are bisexual. While, conversely, it's been increasingly common since the mid-90s for young women to feel they should give bisexuality a try before they can know they definitely aren't attracted to women. But the difference now is that we are telling this to children now instead of young women.
