So, from what I am seeing you are also a straight, cisgender, white man. This is not a bad thing to be.
However, you are vastly dismissing the importance of representation in media. No, it doesn't solve systemic racism or sexism.
But it is still really important.
I'm a bisexual woman born in the 1970s.
I didn't get to see myself on screen, in a major role, until I was in my 20s.
My twenties.
Had I had that representation younger, I would have had a much happier teenagerdom because I would have known it was okay to be the way I was.
Representation doesn't solve other problems, no.
It solves the problem of representation, and it's easy for the privileged not to understand.

Matters.
