Dear Confessor:
The fact you have "pent up frustration" on a topic that has nothing to do with you (unless you have repressed emotions), where you're injecting yourself into a social issue because of your own poor understanding and seemingly hostile attitude is pretty clear enough that nobody would want to talk to you anyways.
Non-binary people, or anyone, are not put here on this Earth to explain "the right to exist" to people who literally get angry at the idea of said group existing, which in your own words you seem to be getting "built up" over time since you can't express your views without repercussions.
If your attitude is literally "if I talk about it I will get banned" then you are either lying to yourself about how you actually feel about this and you clearly have stronger emotions than you're leading on, or you're not mature enough to talk about this without flying off the handlebars, or both considering you wrote to an anonymous confession thread ranting about the topic you are complaining that "you can't talk about".
Here is a hint, if you have fucked up internalized feelings regarding a topic that is inducing borderline rage/ranting posts about said topic, talk to a therapist and don't unload your baggage onto random people who fit the topic of your rant.
