I hate to burst your bubble, but pretty much the majority of British youth is liberal. Very few are conservative and they're dwindling with each passing generation. Conservatives in the UK will become extinct. Don't be surprised that she might be liberal, like 85% of British millennials and Zoomers are liberal.
It's not really political, there are other things that are non-political that are authoritarian and radical, like animal rights, militant veganism, and Religious extremism. And they're being spread by the internet.
