The fight for trans rights very, very much existed in the 1990s. To suggest that trans rights is somehow a recent phenomena ignores a whole lot of history.
Wachowski, AFAICT, doesn't tie the movie to trans rights as a political issue (though that had been an issue, though with very little public traction, for quite a while before the movie was made, so if it was going to be addressed in a major motion picture, doing it indirectly and subversively would be natural and necessary). It's incorrect to equate any story about that groups experiences, whether literal or metaphorical, as necessarily being about some political issue involving the group, though it's a common mistake for people outside the group whose only attention to the group is political to make that mistake.
Yours: ... people lie sometimes?
Why are you a more authoritative expert on this topic? If you don’t feel you are, can you point to someone who is that agrees with you (producers, actors, etc)?
If you can’t, why does this artist explaining their artistic vision feel like something you need to disparage?
