It’s not a new thing for a horror movie to make reference to the socio-political issues of the day.
What may be new is horror movies making very blatant connections to current political arguments with stereotypical conservative or liberal types interacting with each other until something shows up to kill them. YouTube channel Acolytes of Horror looked into that.
Now, the channel host does have a political perspective of his own, and he does eventually share it, but the issue as he sees it is these movies are generally only surface-level political in the way they present issues. See below for details.
