Why does Times publish falsehoods?

Again the question: Incompetence or Dishonesty?
Please see the link at the top of the blog.
Someone has a book and a film titled "Not Evil Just Wrong."
The nice people producing them believe, and want us to believe, the "global warming" scammers are not intentionally telling us falsehoods, that in fact the "global warming" proponents do also believe what they are saying, but are, simply, wrong.
Is that what we should in turn believe about the people who produce the Times editorial page?
That they believe their hogwash, but are just uninformed? Or dumb?
On said page for Wednesday, 21 April, there is a letter with this sentence: "Rep. Randy Neugebauer called Rep. Stupak, a leading right to life advocate, a 'baby killer' while Stupak was addressing Congress."
What Rep. Neugebauer said was, in fact, that the bill was a baby killer, and he explained that and apologized to Rep. Stupak, and some "news" organizations did report the facts.
Now if I, a very limited consumer of "news," can know that fact, why can't the editors of this alleged "news" paper know it?
And if they know it, why do they allow a falsehood into print on their editorial page?
Yes, I realize it follows their tradition of allowing their cartoonist and their syndicated columnists to call Tea Party people "racist," when any honest or sane person knows that also is a falsehood. (To repeat, just in Memphis and in Mississippi, there are three Tea Party candidates who are black, a fact easily knowable to "news" people in Chattanooga.)
The mis-called editors botch the heck out of grammar and punctuation and change well-written and accurate letters frequently. So why can't they correct genuine errors, why don't they avoid falsehoods?
The same letter continues the apparent falsehoods about some congressmen being called racially disparaging names, although no one has offered any proof, and at least one person who was with the alleged victims said it didn't happen.
Why, to ask again, though expecting no answer, why do the editors of the Times editorial page continue to publish blatant falsehood?
Letter writer John Bratton, of Sewanee, might be blind and honestly ignorant. He might have an excuse to write such inaccurate garbage.
The editors have no excuse. They must know they are publishing falsehood.
