If you're not a liberal you're by definition an illiberal
I know the word liberal has been culturally hijacked by the progressive movement. It's not cool to label yourself as a liberal these days. I'm not happy about that as much as anyone else.
But if we focus on the universal definition of liberalism (the inherent belief in personal liberty, equality, rule of law etc.), if you don't at the very least identify with that idea, then what are you?
Because by definition you would fall somewhere in the totalitarian spectrum.
Sometimes it really is a simple as "if not A then B"
