You are so right! The Crusade were an overly zealous result of the Muslim hoards invading north Africa and forcing all in their path to convert or be put death by the sword. Then they moved north into SE Europe and actually reached the outskirts of Vienna before they were defeated by the Polish army led by Jan Sobieski! So much for the enlightened bigots who always belittled those "stupid Poles".
Some people never learn their history, and as the old adage says, "They will live to repeat it." Unfortunately, the rest of us will suffer alongside the idiots.
Someday someone will write a book entitled: "How the Poles Saved Civilization...Numerous Times!"
To my mind, every school child should know the name Jan Sobieski. And every school child should know the name Jozef Pilsudski. And Lech Walesa. And Karl Wojtyla. Shall I continue?
God bless Poland, the Christ of Nations.
