In my opinion, the sudden uprising against drag is a direct effect of the sudden uprising of public homophobia and transphobia among the right in the United States.
Prominent thought leaders and other figures on the right are openly queerophobic today in ways that just didn't happen even a few years ago.
A decade ago, most people in the United States were hesitant to express homophobic views in public because they knew they would take a lot of shit for it.
Donald Trump and his right-wing miscreants tore down those walls of social disapproval. And now, even with Trump fading from power, his supporters' normalization of open hatred continues to grow.
