Unless there’s an expert who can tell me that no, if they’re diagnosed that way they have to be that way, in which case I’d question them as an expert. The brain is complex.

do you not think it’s rude to tell someone who identifies a certain way, that they might change their mind? do you not think it’s rude to act like an expert on their experiences, more than they are? do you not think it’s rude to act like their opinion on themselves only has merit if science backs it up, but act like your opinion is somehow above that standard?

when someone identifies as a different sexuality, as a different gender, it’s polite to give them the basic respect of acknowledging it. any of these things may change, and it’s OK if it does, but it’s very rude to point that out, as if they’ve never had that thought. it’s also invalidating - consider telling a trans person they might reconsider their gender. identification along the aro or ace spectrums deserves the same respect

respectfully, i would ask that you stop commenting on this situation, and reconsider whether your advice is actually contributing positively to the conversation
