You got all mixed up. Mr. Potter was criticizing the poor communication that cause the traffic chaos during a storm.  This kind of comment is totally different from saying "all jews are pathologically greedy."  Mr. Potter's comment is neutral, simply on the traffic situation. He wasn't saying anything against the French people in Quebec. While your example was a racial remark, a racist bias. 

You can not even tell the difference between these comments. You really should not give any comment. It just indicates how ignorant you are.
