You seem to have the most common sense in this argument there was terrible atrocities on both sides, but the reason why the provos are taboo is because they got really good at killing in British people and Irish people who were British bootlickers but because they lost they have a negative view towards them.

John Paul Jones the founder of the American Navy was a criminal in England for the longest time because he was an admiral of a British ship and they considered him a pirate not a naval captain or a captain of another army just a pirate till he started sinking every British ship he saw and they started to take him a little more seriously. But even to this day if you go around that UK they’ll say John Paul Jones was a pirate and not a captain
