Replying to Canada/ War

My friend's mom just opened up a teaching store and she wanted to buy supplies from the states but the guy wouldn't trade with her cuz she's canadian and we're not involved in the war. If any of you Americans are like that and being rude to Canada that's really not fair cuz it was our govt's decision and not ours.

Also I went to USA at spring break and saw a few cars decorated with things like
'let's make Baghdad glow in the dark! Honk if you agree!'
and 'kill them all and let God sort them out!'
That really disgusted me. Maybe I'm wrong though and in that case sorry.
