See we don't have those in France. I'm sure there's some ultra religious and/or ultra nationalist equivalent on the individual level, probably not much difference proportionally, hateful idiots are common the world over, but it's not a politically significant ideology. You'd probably find more of those types in favour of razing Israel to the ground, something certain factions of the extreme left and extreme right seem to find a level of agreement in. Horseshoe theory and all that.
Anyways that's a symptom of the two party system, the extremes have constant political representation as opposed to their rises and falls in multiparty systems. The upside is it's a lot more stable overall.
