I understand that people are claiming this is his argument, but I don't see it. He makes the argument that "men's rights" (and implicitly "women's rights") discussions are emotional, and he's right.

Where's the proof? And if it is emotional and bad nor good arguments are influencing he's simply Glen Beck pandering to a group that simply agrees with him already and inflaming those that don't? If that's the case then bravo for him (and Glen Beck). But then what did he expect then?

You can't argue that this is an emotional issue, emotional issues create a certain response, and good arguments aren't influential -- and then feign surprise when exactly what you state happens. IMO that's a sign of either genius PR at work (ala Beck) or one with poor character (ala Beck).

Again, I don't see this interpretation. As I read it, he says that he believes people can't be convinced by evidence to change a position... and it turns out he's right: http://www.boston.com/bostonglobe/ideas/articles/2010/07/11/....

That means there is no right and wrong, as far as humans are concerned. But furthermore the study actually shows why Adams' position is INCORRECT! The study shows that people who are presented with misinformation have potential to cling to this, even in the face of correction. This strongly argues that we should avoid misinformation in the first place NOT to distribute it equally (or worse even more abudantly, since one can generate more distinct false statements than true statements).

And of course read the actual paper where they say,

It’s important to note that the account provided above does not imply that individuals simply believe what they want to believe under all circumstances and never accept counter-attitudinal information. Per Ditto and Lopez (1992: 570), preference-inconsistent information is likely to be subjected to greater skepticism than preference-consistent
information, but individuals who are “confronted with information of
sufficient quantity or clarity… should eventually acquiesce to a preference-inconsistent
conclusion.” The effectiveness of corrective information is therefore likely to vary
depending on the extent to which the individual has been exposed to similar messages
elsewhere. For instance, as a certain belief becomes widely viewed as discredited among
the public and the press, individuals who might be ideologically sympathetic to that belief
will be more likely to abandon it when exposed to corrective information.

Again, this shows Adams' position as wrong. And also shows why the dissemination of misinformation is bad in that it makes it more difficult for misinformation to be abandoned.

Additionally from the study: Currently, all of our backfire results come from conservatives – a finding that may provide support for the hypothesis that conservatives are especially dogmatic -- although they concede that more work is needed here as they don't have sufficient evidence. But given that Adams's position is historical conservative, I do wonder if evidence against it will simply inspire the backfire effect.

But with all that said, I'm sure I'm wasting my time writing this since any argument, even from your own sources, surely won't change your mind in the slightest. It will in fact likely just strengthen your current position -- especially on something so emotional.
