I think you've misunderstood, I include the Top14/D2 in league finals of higher importance to me than the 6 nations, same with Champions Cup, etc. I always thought the French clubs did well in European competitions, not to mention the likes of Russian sides being allowed to play (express themselves) too. The 6N competition is stagnant and devalued, France and Italy aren't enough (but this is another discussion altogether... the game could be grown and value added by making the competition closer to soccer's euros IMO).
A theme that seemingly runs through all the French posters here is that they seem to think it's anti-French sentiment when it's nothing of the sort, not even close. I'd say the same if it were any nation. If as was previously claimed there aren't any rules regarding forfeiting fixtures then there really should be and now seems a perfect time to bring it in or at very least have that discussion.
