"Nothing outweighs our bigotry."
Toward the end of WWII, you'd expect the Nazis to start shifting their dwindling resources away from the Holocaust to deal with real military threats. But no, the pace of killing actually increased: they really, fanatically believed that random Jews they already had imprisoned were somehow thwarting the war effort, so unrelated things would improve if they only murdered more Jews.
If faced with a real existential threat, the transphobe mob would do exactly the same. They'd just embrace their crazy hatred more tightly.
