I worked for a utility company in the south as my first job at the US. I left in late 2015 for a lot of reasons but the big one was a large majority in my (maybe 15 person) office were already big Trump supporters ("I'm glad someone's standing up for ordinary white christians"), and I was straining not to give myself away as a liberal.

The final straw was I had lunch with a regional director and he went on a long rant about how Isis was running europe and how mad I should be at immigrants because I did it the right way etc etc. He even told me my wife (who was born in the US to US citizens) wasn't a real american because her parents weren't born in the US.

So yeah, depending on where you work, I could totally see someone having this conversation in the hallway multiple times.
