Makes me nuts also. When I teach on the Supremacy Clause and bring up the invalidity of sanctuary cities and legalized marijuana, college students look at me like I have three heads. Many of them can't fathom the simplest concepts of federalism, they'll say stuff like "But but but the state voted on that, the people have spoken!" Then they say "Well then how are they getting away with it if it's unconstitutional and illegal, huh?" I then ask them if they were speeding when they drove to classes that day, and ask if every one of them were ticketed. Ignorance of the basics of our Constitution makes my head want to explode. Trust me, though, most of them can rattle off lines from the latest Thor movie, have half the script memorized. And they can tell you in great detail about cheats in Roblox.
