None of us can understand anyone. That's basically what you're saying. All of us only understand anything by analogy to our own experiences. That's all we ever do. About everything.

So I don't understand what it's like to be Black.

I don't understand what it's like to be a man.

I don't understand what it's like to be old.

I don't understand what it's like to be disabled.

I don't understand what it's like to not speak English.

I don't understand what it's like to be someone other than myself, whether that's a young cis bisexual female with almost my exact life experience or someone with completely different life experience.

So?
