No political party in the 1980s or 1990s, except the occasional fringe one, was actively whipping up antipathy to the French minority in Canada. You can’t make a country work that way, even if it does yield some crucial votes.
Of course, making the country work isn't the point. That's too much like committing sociology.
The point is to win. When you win, you can do what you want, and what you've done to win gets validated. Everyone else is thinking the same thing, you know. It's survival of the fittest - that's all the validation you need.
And because there's no such thing as society, there's no such thing as societal consequence. Right?
Each to their own - that's all there is.
