People who hate Justin Trudeau really like other people to know that they hate him. They put stickers on their trucks.
People who don’t feel too strongly either way about Justin Trudeau don’t shout about it, or reply in online conversations about it, or wear shirts about it.
There is no sticker for your car that says: “I don’t love or hate Justin Trudeau — I like some of what he’s done and dislike other parts. On the whole, he is not a disaster.”
