I've never seen this quote in its context before (an article criticising men's rights groups for complaining about their own problems). Here's the offending article with some of Adams' explanation:
But perhaps I can summarize my viewpoint so you can understand why I'm such a misogynist asshole douche bag. Here's my view in brief:
You can't expect to have a rational discussion on any topic that has an emotional charge. Emotion pushes out reason. That is true for all humans, including children, men, women, and people in every range of mental ability. The path of least resistance is to walk away from that sort of fight. Men generally prefer the path of least resistance. The exception is when men irrationally debate with other men. That's a type of sport. No one expects opinions to be changed as a result.
Are women more emotional than men? I'm not sure how you measure that sort of thing. On the emotional scoreboard, does one person's anger equal another person's excitement? All I know for sure is that the Men's Rights group I poked with a stick has some irritable dudes.
I guess he's mainly saying that men's rights advocates are kind of dumb because on balance, they get a pretty good deal out of the inequality. Men (especially simplifiers like Scott Adams) don't care much about a lot of what goes on around them, so their best strategy is not to weigh in when faced with people who are more emotionally involved (such as women, children and disabled people). I get the idea that he isn't on board with a number of areas of feminism, but here he's just telling MRAs that they're just pissing in the wind. They should just sit down and shut up, if for no other reason than that there's no benefit to bringing your own relatively minor issues to this argument (especially as they're often voiced by people who aren't affected by them much in the first place).
@Dr_Awkward I realize I might take some heat for lumping women, children and the mentally handicapped in the same group."
It's his talent for understatement that keeps me coming back for more. Maybe he should listen to his own advice?
