My low rating's not for history as a subject but the way it's taught in school, usually as state propaganda i.e. bigging up one's own country as a paragon of all that is good and virtuous and making out other countries to be backwards, nefarious, evil. etc. Fr'instance when I was taught history at school (in the UK) we were told how the Empire brought technolgical advancement, education and good old christianity to the rest of the world. No mention of its role in the slave trade, persecution of other faiths and dodgy goings on in India etc. I guess similar bullsh*t is spouted off in every school around the globe.
