I agree. Tipu is a hot topic among Coorgis. Even the Konkan Christians hate him. He was quite a religious fanatic, converted thousands and punished those who didn't. But at the same time, he left many temples unharmed and had Hindu generals in his army and he himself reported to the Mysore Maharaja (Wadayars) for most of his life like his dad, Hyder Ali did. So it is all muddled w.r.t Tippu Sultan.
I have witnessed how the Kodavas (and yes, it is strange, some call themselves Hindus, but most say they are Greek descendants from Alexander's lost army

hate Tipu Sultan and Coorg becomes a hotbed of Kodava-Muslim clashes around Tipu Jayanti. Why do you think Coorgi Pork is so famous?
I personally think Tipu was a king who did what was good for him at that time. He fought everyone who threatened his power(British) or didn't yield to his power(Kodavas and Konkan Christians), which was the norm for any king. Should we celebrate his birth anniversary? That is debatable and depending on which government is in power today (Congress/JDU/BJP) you'll see different takes on this.
Personally, I love history as a neutral enthusiast, enjoyed my visits to Srirangapatnam and was amazed watching the palace of Tipu Sultan, where he ruled, fought and died. I marvelled at the scientific advancements that Tipu made regarding warfare, the gem studded pillars and thrones, the Kaveri river next to the fort, surrounded by trenches filled with crocodiles, the tiny, dark prison cells, all the underground secret passages, how the British got inside the fort, the story of betrayal by his treacherous minister, Tipu's sacrifice of his elder son, Tipu's many body doubles...the stories are incredible and will make a fascinating movie/tv show!
