Who actually real terorist?

A German Muslim scholar when he was asked about terrorism and Islam :He said :Who started the first world war? not Muslims ?Who started the second world war ? not Muslims ?Who killed about 20 millions of Aborigines in Australia ? not Muslims ??Who sent the nuclear bombs of Hiroshima and Nagasaki ? not Muslims ??killed more than 100 millions of Indians in North America ? not Muslims ??Who killed more than 50 millions of Indians in south America ? not Muslims ??Who took about 180 millions of African people as slaves and 88% of them died and were thrown in Atlantic ocean ? not Muslims ??No , NOT Muslims!!!First of all, You have to define terrorism properly...If a non-Muslim does something bad..it is crime. But if a Muslim commits the same..he is a terrorist...So first remove this double standard...then come to the point!!! , .
