There are obviously going to be some cases of that. I remember hearing through a friend that their university roommate from France dropped a class at UQAM because they couldn't take their lecturer's accent seriously. You have elitist people elsewhere.

When visiting France I had one experience where I felt like I was a zoo animal, like that. Walking around a public site a woman got very excited like she found the answer to a tricky riddle and yelled "Québec, Québec" at me. She was so sweet though and it was harmless so I didn't take it even the slightest bit poorly.

Most people in France knew better than to make a stink about it. I talked with plenty of people and occaisionally it popped up but more as a passing curiosity, I didn't feel like it wasn't outside of natural curiosity. Things like "pas pire" raised eyebrows "stationner mon char" rather than "parker mon auto" sometimes took people a minute to comprehend.

All to say, there are some rude people everywhere, but my own experience in French with a Québec accent was great.
