Interesting thread.
BLUF: Life is what you make of it.
As an unilingual Anglophone I was posted to the FMC HQ St Hubert (outside of Montreal) in the early 1990s from Petawawa. I worried because of the perceived hatred by the French towards the English, but this was offset by the possibility of meeting gorgeous Quebecoise women. When I got there I had the guys start teaching me simple phrases like ordering a pizza and so forth. They eventually put me on a half day French course three times a week. I was introduced to a beautiful Quebecoise, married her and started a life long intensive French course with her. Over twenty years of marriage, three children, eight moves I can't be happier.
In general I've not a had a problem with the French vs the English thing. You can think that a lot of negative kinds thrown at you but perhaps this your defensive screens being thrown up and you're being too sensitive.
Enjoy life, enjoy the adventure.
