It is Islam. There is only one other culture that wants all other cultures dead. If there is, let's add it to the Islam list.
Other than Islam, other cultures are fine. There food is tasty.
But Islam isn't another culture. It is a culture killer.
I won't argue with you there... They have a millennium of trying to kill other cultures.
I've got one to add to the list - Communism/Socialism.
It's the other, newer, equally as bad viral philosophy.
