How did Netflix know I was gay before I did?

I think the answer is pretty clear - Netflix made them gay.

But seriously this is nothing more than a person coming to terms with their sexuality and having an audit trail of media they consumed during that time . They drove the algorithm as much as it drove them is my guess.

There is a point where we are not really aware of who we are or why we're here. Then there's a point where we know who/what we are, but we can't really put a name to those things. Putting it in words, giving things names, these are pivotal parts of self-realization, but that knowledge existed before we knew what to call it. So it's not surprising that in this lady's journey of knowing herself that she was subconsciously aware of a thing, and perhaps acting that out unknowingly too, before she could decide to "come out of the closet" in an official way, and name the way she felt.

The real question is, how can Netflix tell their queer content apart from their regular content?
