What exactly is wacky about limiting legal immigration and/or asylum if that is what the citizens want? IMHO, Those don't seem like insane ideas when there is crazy amounts of unemployment in the country.
Being apathetic to politics is consequential in and of itself.
As to your claim about immigration, I'm not interested in defending any particular policy position. But, there is some research that indicates immigration boosts overall labor participation [1].

It doesn't help your case when you lump arguable, but sane positions with denying climate change.
They're particular to the modern conservative party.
Many of my liberal friends believe in crazy stuff like russiagate or defending BLM looters/rioters or proudly voting for a political candidate that supported bombings in the middle east that lead to the death of countless civilians (including kids) while simultaneously villainizing Dubya for being a war mongering criminal.
You'll have to excuse me for not seeing your "clear delineation" - whatever that means.
