Those seem like typical reactions of young teenagers, and I assume that they are, given that you are very young yourself. I’m going to just come out and say that this doesn’t necessarily mean they are against it. They might just not know how to react.When I tell people that I'm non-binary, they completely ignore me. But when I tell people that I'm bisexual, they're like: "Oh my god, you like girls??" That's why I don't tell people about it anymore, why can't I just be accepted? :/
Not sure if this is supposed to be in the "What's Bothering You?" thread instead.
However, I’m not aware of the complete details of the non-binary situation. Did you tell them because you want them to use a particular set of pronouns? If so, how they react to that tidbit will tell you a lot more. By ignoring, are they ignoring your preferred pronouns or just unaware of how to react to the fact that you are non-binary?
