The extra challenge stalemate adds can be interesting, I don’t deny it.
It’s just that if a player is in a position where they can’t do anything beside suiciding their king, they’re obviously not winning, and it seems a little bit unfair for the other player to consider the situation is equal and that noone can be designated as the winner.
This doesn’t invalidate your point whatsoever, obviously, but what Le Pen exactly said is “Les chambres à gaz sont un point de détail de l’histoire de la Deuxième Guerre mondiale”, which basically means that they do existed, but wasn’t that big of a deal. Which in a way is actually even more insulting.
