I highly doubt you’d be banned for that.
But yeah, that not only sucks, it’s just plain stupid. In a world where everyone’s self identity is paramount, it’s unbelievable that your own identification of your sexuality is deemed wrong because of an incongruity with someone else’s self-identification. (Even if your perception of why you were banned is inaccurate, it’s still dumb that anyone would insist you’re gay based on someone’s non-physical gender identity.)
