In addition to what others have said, I'd add that the writing profession has a high percentage of liberal, left-leaning people in it. It's just the type of people it attracts. The world of writing is largely filled with left-leaning teachers, editors, writers, critics, and publishers. So, in addition to the quotas and "woke points" that others have mentioned, part of what happens here is just the percentage of the draw. When you hire a game writer, chances are good that you're going to get someone who sees the world through a left-leaning political-cultural lens - because that's how most writers are these days (especially the younger generations).
