I am not sure if you found this disturbing as I did. Here, the Rev. Thomas J. Euteneuer, president of Human Life International, says "Warren Buffett will be known as the Dr. Mengele of philanthropy unless he repents and ceases using tax deductible donations to promote a culture of death and desolation."
Now as you expect I have much to criticize Buffett about concerning his pro-death philanthropy. However I must object to comparing him to Dr. Mengele. Dr. Mengele did far worse things than Warren Buffett will ever fund. He committed far more unspeakable crimes. The inapropros comparison, I think, not only falls flat but risks only alienating more moderate voices and embarassing the cause.
There is a saying on Usenet (the traditional forum for discussion on the Internet) that a thread has reached the end of its useful life when people start comparing their opponents to the Nazis. It's very true. At that point the discussion has completely and totally degenerated into something utterly unprofitable. Unfortunately it applies here too.
Reading other parts of his message, he says, "The merger of Gates and Buffett may spell doom for the families of the developing world." I'm not sure what to call this — it's not quite demogoguery, it's not quite sensationalism, maybe rabble-rousing — so I'll just call it nonsense. "Doom" implies total destruction. That is not going to happen, that is just patently absurd. Much less are Gates and Buffett going to cause it. It is said that there are two errors you can make of the devil — give him too much credit, or not give him enough. Let's not give Gates too much credit.
HLI has always been a somewhat shrill and strident organization, in my opinion. Rev. Euteneuer has proven a close follower of Rev. Marx, his predecessor.
I say strident language is not going to get us where we want to go. And I'm not afraid to criticize an ally on that account.
UPDATE: Apparently the reason Buffett was called "Dr. Mengele" was because of his eugenics activities. While this makes a certain amount of sense, I still object to the association. It would be better to call him the Margaret Sanger of philanthrophy, though that certainly doesn't have force. :-)

So what has Buffet done to deserve this over-the-top as well as your moderated criticism into the culture of death? You have posted nothing here or previously. And if I am not mistaken, don't you proudly own a partial share of Berkshire Hathaway?
I owned a full share, thank you very much (though I think it was Class B). I sold it though once I found out what he was into.
Warren Buffett is rabidly pro-abortion and supports abortion causes overseas. He also supports the usual array of family planning in developed countries. According to HLI he has openly supported eugenics.
He is giving about $3.1 billion to the Susan Thompson Buffett Foundation. According to the WsJ, 'The Susan Thompson Buffett Foundation has been a quiet force in the controversial area of population control, making substantial donations to supporters of abortion rights, such as the Center for Reproductive Law and Policy, the National Abortion Rights Action League and Planned Parenthood. The foundation also has given money for the development of mifepristone, the key ingredient in RU-486, also known as the "abortion pill."'
Sad to say, Buffett has given money to an organization that makes suction pumps for abortions, for overseas distribution. That's direct subsidy to abortion. See my post about it.
I was out riding on July 4th 2006, trying to find-out why they didn’t have a ‘Go Fourth’ at WU, and found a dead, baby doll with one arm on Mayberry Street, the other one was broken-off. I guess you could make TEN-thousand-one statements of what that symbolizes. I hung it up on a hook, which is how I wanna be martyred (hung, shot, guillotined, or pulled-apart by four-horses when a shotgun is fired. Guess you‘d call that ‘Quarter-Horsing-Around’). Nevertheless, my interpretation is this: America, in it’s infancy, has no bloody idea of how much we owe the King of Kings, God Almighty, for our well-being in this Land-of-the-Free; That also makes me realize, by her lying broken in the street, how blatantly callous we are toward the unborn, as girls in short-shorts practically wanna. Who the Hell is Jesus? There were monks, too, in the Middle Ages, even now, who had literal skulls on their desk to remind them they were passing-away. Don’t know? Don’t care? “SoBeIt,� saith the Trinity. “Let the Angel of Death descend.� --- I'm very angry due to our happy society which replaces God with MSNBC.
