It occurs to me that a reason for insanities like doubling down on political correctness and pretending that men's inability to use women's restrooms is a long-standing civil rights issue that needs solving now is because the leftist belief system has no room in it, no mechanism for dealing with existential threats. A major component of their ideology is that we can achieve universal peace on earth if only people would take the time to understand each other. Islamic terror does not fit that ideology. Islamists don't care if you understand them, and they understand that you are an infidel and must die.
In short, the left is utterly incapable of solving the terrorist problem. And they resort to inanities because they truly have no idea what to do.
Progressives, like jihadis, want to see our culture destroyed. And what more effective way to do it than by letting the barbarians through gates by the millions. So it's not just that the Left doesn't know how to deal with the existential threat, they actively court the threat with the intention of getting a twofer out of it -- 1) the destruction of white "bitter-clinger" culture, and 2) converting the death cultists to their Marxist cult, figuring (naively) that giving the jihadis cradle-to-grave bennies will cure them of their barbarism.
