“If lots of trans people are enormously upset by what you’ve written, then maybe you screwed it up. Maybe you are marginalizing trans people, even if you didn’t mean to. Maybe they read something into your blog something that was there, even if you didn’t mean it to be. Maybe you did hurt people — actually, no “maybe” about it, clearly you did — even if you didn’t mean to.”
And not meaning to doesn’t excuse you anyway.
