Generation Z is insanely liberal but that's because the goal posts of what makes somebody a liberal have changed
Old boomers think that gay marriage and universal health care are liberal issues while Generation Z thinks both are normal and okay. For Generation Z, truly liberal issues are weather or not there are things such as gender or weather or all drugs should be liberal.
Anyone who thinks Generation Z is conservative is too often comparing it to today's conservatives. Hell...by the time Generation Z is all grown up, they'll be arguing about weather or not there are 80 genders not about Roe Vs Wade
What remains to be seen are trades, immigration, abortion, death penalty and gun control.
I would not be surprised if Gen Z opposes trades and wants to restrict even legal immigration more than previous generations do. It's not just a matter of expanding the goal post. In the Philippines, younger people are more likely to support drug war.
As for gender identity, if it reaches the point of oversaturation, there will also be a war on transgender people as well at some point.
Nothing is permanent.
