Muslims want to end (our) belief in God and replace it with theirs.
I'm not sure if Islam fits Marxists/Socialists/Communists catagories, but I believe in not too many years they will control the U.N.
Most likely they will and most of the world too. Seems they are taking over most of the world through violence, especially in Africa.
"Islam dominates above the 10th parallel, on a line that splits many nations in half. The northern portions of countries like Sierra Leone, Ivory Coast, Ghana, Togo, Benin, Nigeria, Cameroon, the Central African Republic, Sudan, Chad, Ethiopia, and Somalia are Muslim. Southern parts of these countries are Christian or other religions."

Believe it or not, the Muslims are our allies in the UN in regard to Abortion matters, sadly, many Catholic/Christian Countries are for Abortion and vote that way in the UN.
