I'm personally glad the crusades happened, since the alternative would have cost a lot more suffering. The crusades were a reaction on the enchroaching of Islam on the European continent. If we'd live under muslim leadership like pretty much all Arabic country we'd have much slower progress with science, technology and human rights. Thanks to Christianity, the Enlightment was possible in Europe. In Islamic countries…
Wow, racist much? "Christians be like this, Muslims be like this " There's a lot of ignorant assumptions going on in your post, but let me just remind you that those "unenlightened muslims" are those to whom we owe modern mathematics.
Please don't abuse terminology.
