Which is why I bring this up.

If you are cis you have the privilege of not having to look yourself in the mirror everyday and say "no" to a society that wants to drag you down for your gender. Instead of worrying about people like JKR and making a big deal about how wrong she is (burning her books). Spend some time reflecting on what power you have in your own life and how the bias and hate toward trans people that you DO have in your heart manifests in denying personhood to trans people.
