I would be disgusted, but probably privately so.

I hope I'm carrying a drink, a hot one.

'bout the same as when I saw a "fuck Trudeau" bumpersticker, or for the last few years, a Canadian flag...

One of my classmates has a leather jacket with a big US flag stitched on the back. He was asked to take it off.

I think I’d walk up them and call them a traitor, and maybe imply that if the US comes for our sovereignty, I’m coming for them. I’m angry.

I would be enraged. I wouldn't do anything except be enraged, because I'm a law-abiding person and spend a lot of effort remaining that way.

I would want to react in certain ways, but it's just not worth it.

I've seen a couple of trucks recently on my commute with trump flags/signs. It makes me exceptionally angry. I have to concentrate hard on remaining calm. It's a genuine challenge.
