Not that I know but that doesn't exclude the possibility of lost souls trapped and heading the wrong way.... as u know these Nations aren't given the opportunity to defend their core interests whether that is, their economy, know how and land or their culture, language and traditions in a civilised way just like Wales, Scotland, Jersey or the Frisians do and the result is some extreme cases some folks may be tempted by some extreme views keeping in mind two things are essential, first the French state has always encourage indirectly or suscitate these type of behaviour as it gives their authority a nice edge to deny these Nations any collective or individual rights using any type of incident to throw dirt at them, second individuals involved with extreme political views from these Nations are very few. All studies showing they seem to damage themselves through self destructive behaviours more than anything else.
