Is Gun Research by John Lott Discredited?: Responses to Media Matters' false claims

Note that I have tried to make many of these responses after the posts that Media Matters has made about me, but they do not allow me to put them up in the comment section.  I have tried putting out these points on twitter or in a few Fox News op-eds, but Media Matters never responds to those discussions, presumably because it would draw attention to my responses.  Unfortunately, as I have discovered over the years, Media Matters is uncritically read by many in the media, and possibly that is another reason that they don't allow my responses to be posted.  I also think that by constantly posting discussions about me being "discredited" they hope to influence Google searches (see the screen shot below from this morning showing a total of about 160 posts where they attack me (some of the 172 are not really about me)).  Anyway, here are some of my responses:

"The Nine Worst Claims About Guns From John Lott's New Book." -- response is available here.

"Who Is Gun Advocate John Lott?" -- response is available here.

"Mother Jones and Media Matters bungle study on Mass Public Shootings" -- response is available here.

"Why Is NY Times Citing Discredited Gun Researcher John Lott?" -- response is available here in the section labeled "update".

"Gun "Researcher" Pushes Sham Statistics In The Wall Street Journal" -- response is available here.

"Discredited Gun Researcher John Lott's Failed Attempt To Correct Obama's Gun Statistic" -- all one needs to see is the Washington Post Fact Checker article available here.  Kessler is making a similar argument to the one that I made here.  Will Media Matters attack Kessler in the same way that they attacked me?

Other responses to Media Matters by me:
Media Matters, 'Stand Your Ground' and me 
David Brock, Media Matters and gun control hypocrisy
MEDIA MATTERS' POTENTIALLY LETHAL DISTORTIONS ON GUNS

"Media Matter's dishonest attacks on Fox News" -- discussion here.

Often Media Matters and others will point to one single paper or two that criticize my work.  In fact, there is a large academic literature that exists on these topics, and when you look at the whole literature you will see that most academic peer-reviewed studies support my findings (see a list of published research in Table 2 available here).

My newest op-ed at Fox News: Fact vs. fiction on background checks and the gun control debate

My newest Fox News piece starts this way:

Will Senate Democrats be able to end debate on their new gun control bill Tuesday night? President Obama says that it is “not right” to continue the debate. But he might be more afraid that Senators will point out all of his false claims and reveal the gun control bill’s dangers. 

Mr. Obama got it all backwards in his April 3rd speech in Colorado: "tougher background checks . . . won’t infringe on the rights of responsible gun owners, but will help keep guns out of the hands of dangerous people."  

The president kept claiming this week and last week that: “as many as 40 percent of all gun purchases take place without a background check”  and that "background checks have kept more than 2 million dangerous people from buying a gun.”  But both statistics are false. . . .
