There hasn't been any significant "crazy liberal" politics in this country for many decades, at the very least.
"Crazy liberal" would be things like actual in-national-office politicians advocating for nationalizing all businesses, seizing the assets of the rich, etc.
Advocating for all people to have basic human rights guaranteed to them is not "crazy liberal," it's common sense and common decency.
