CHILUL HASHEM

I SEE IN THE PAPERS AND ON THE INTERNET A LOT OF PEOPLE DISCUSSING  CHILUL HASHEM AND KIDISH HASHEM
I WAS ON A PLANE YEARS AGO AND THE PEOPLE IN THE ROW BEHIND ME
WERE GOING TO EAT A PORK MEAL
FROM BRITISH AIR WAYS
WHEN I TOLD THEM THEY JUST SAID MIND YOUR OWN BUSINESS BY CAUSING AN ARGUMENT IN THE PLANE I AM MAKING A CHILUL HASHEM
I SAID AS A JEW THERE IS NO SUCH THING
MY DUTY AS A JEW IS TO OPEN MY MOUTH AND OBJECT TO THEM EATING PIG
THAT IS A KIDISH HASHEM IF I KEEP QUIET I AM MAKING A CHILUL HASHEM
IN THE END I USED  LANGUAGE THAT STOPED THEM EATING THE NONE KOSHER MEAL.
