Unfortunately, racism is an ingrained part of not just America, but nearly every culture in the world. “Us vs. Them” is a very easy mentality to fall into, and skin color is a very obvious trait of every person. As to BC specifically, you’ll likely find that there’s more racists here than in some places, but fewer than in others. Not that any racism is acceptable, but it does pervade American society and it’s hard to know who is going to have what political or social opinions before they come here.
