I love the blind rage her statment came across to all the right people for all the right outcomes.
You hear it, think it's kinda weird, then remind yourself you follow this idol to watch her grow, get accomplishments, experience, and confidence to be the person she is meant to be--and youre there for as many steps as you can. Shes meant to be inspiration that this nobody can make it with encouragment and support, even if you may never see face-to-face.
Or you can throw a tantrum that a woman might imply that youre not the perfect being or somehow superior to her in every conceivable metric, even though you mire in your filth, accomplishing nothing, growing cold and resentful of those with aspirations and talent. I know it's hard, but seriously ask yourself "what did she mean by this" unironically. Shoot for three answers to this. Hopefully you will keep to your oshi and grow with her, savoring successes and basking in virtual camaraderie. Noone will fault you, or necessarily care, if you chose to take the statement maliciously and seethe endlessly in this imagined slight, but please do so quietly.
