On the French and British "Logic" (Post WW1) Which Stated that it Was OK for the Czech Population of Austria-Hungary to Secede from Austria-Hungary but Not OK for the German Population of the Sudetenland to Secede from Czechoslovakia

There wasn't anything logical about a damn thing that France or England did before, during, or after WW1. Whether it be their secret alliance leading up to the war, the way that they served up their troops as disposable dish-rags in battle after batter, or their punitive treatment of Germany through the Treaty of Versailles, it was ALL lunacy and, so, no, there wasn't anything even remotely logical about this action as well. Nada.
