Follow through the three pages and you will see quotes such as this:
But not all the news is bad! UN agencies, such as the United Nations Children's Fund (UNICEF) and the World Health Organization, have worked hard to improve the lot of children.
Adoption agencies, orphanages, SOS Children's Villages, UNICEF, and similar organizations or groups serve a good purpose when they try to provide support to underprivileged children.
and my favorite...
Under God's Kingdom humans will be enabled to rear children in a balanced way. (Job 33:24-26) Young folks will be raised in the spirit of peace and universal brotherhood, the ideal set forth in the UN Declaration of the Rights of the Child.(Psalm 46:8, 9) Never again will there be the need for an International Year of the Child or for a Convention on the Rights of the Child.
I now see the evidence that the WTBTS has given support to the UN and its agencies without putting the words "Satan's Organization" and "disgusting thing" in the same sentence. Very disgusting indeed.
