C-FAM's Friday Fax tells the title story. The nub:
The argument began with passage of a Lithuanian “Law on the Protection of Minors against the Detrimental Effect of Public Information” which prohibits promotion of “homosexual, bisexual, polygamous relations” among children under the age of 18. While the Lithuanian president subsequently vetoed the measure, the Siemas overturned his veto and the law is slated to go in effect next March.
As a consequence, in September the European Parliament (EP) voted 349-218 to condemn the new law and ask the EU Agency for Fundamental Rights to review it.
So, the EU can't allow a nation to NOT push the homosexualist agenda on children; you MUST do it.
Catholic Family and Human Rights Institute (C-FAM) president Austin Ruse writes about exactly this sort of growing interference of "transnational progressives" in family matters in the January 2010 issue of Touchstone, by the way. And it's not just the EU. It's our beloved UN too. (Beware signing new treaties...look at the fine print.)
The Lithuanians insist they are free to enact such laws and that the European Institutions have no “competence” in them. Many Europeans have long feared what they see as inevitable EU interference in life and family matters.
