I care. Pretending intent doesn’t matter just allows the hatred this mod creator has to grow. They didn’t make that change in good faith, it’s a common dog whistle for right wing bigots. Around 1% regret transition, and often because of backlash from those around them, not because they’re not trans.
When someone’s intent is to criticize and invalidate a trans person’s very existence, I care. And obviously plenty of people do since the mod was removed.
