Counterpoint: you can absolutely self identify as an Ally. For example, I self identity as an Ally and there ain’t shit this adorable platypus can do to stop me.
I’m an Ally because I choose to be, by my words and my actions and the example I set for my children every day. I don’t need an attaboy from any marginalized group to confirm I’m on the right side of history. We do what’s right because it’s right. Full stop.
