Lol ! U can celebrate a fella who insult , kill the kaafir ans destroy their place of worship for all o care . Problem is the hyprociy of declaring islamic terrorists having nothing to do with religion.Cry me a river.
Anyway, you should at least be happy we are celebrating a Muslim ruler who is ethnically from the region. Other than Tipu, we don't usually do that (ethnic rulers of mixed descent don't count, since most of you guys still don't view them as of the region).
