You are making a shortcut. There are probably various reasons why people favor a candidate, and you should not underestimate the "I hate the other one even more" factor.
> French people going on about how muslims should all be imprisoned
This is a preposterous statement. Even the FN's proposed policies is not about putting folks in prison, but to make them leave the country if they had the power to do so. Plus, French prisons are already over-capacity and most prison sentences are not applied because of that. Do you know what you are talking about or do you read tabloids?
