Fair enough. The language was intemperate, and I did check afterwards and saw that you've contributed real information to Slashdot (as well as some politics that I disagree with but am willing to take as sincere). More useful posting history than my own, certainly.
I usually don't bother to post responses to things that seem dumb to me, because who has the time? However, a pet peeve of mine is willful presentation of lies crafted to seem like "evidence" to back up a position. It makes it so much harder to find out what's really going on, and I'm enough of a positivist to think that we can make good fact-based decisions if we don't pollute our information sources. Occasionally something jumps out at me. It seemed virtually certain to me that the examples you gave were bogus, precisely because they seemed too dumb to be examples of real propaganda. What they look like is crafted material designed to convince an unsophisticated reader that propaganda was afoot, because they look like what such a person would do if they wanted to create propaganda. I find that whenever I actually bother to check out things like that -- and I read a range of sources, from Infowars to Newsmax to Fox News to the NYTimes to Daily Kos (and some fringier left-anarchist stuff as I find it) -- they are inevitably bullshit of one sort or another. This has been so universally true in my experience that I assume things that look like that are false. Unfortunately, at the time I responded, it seemed like the examples you gave were being taken seriously, so I took the unusual step of actually checking them out and responding. If I'd shown up a little later after there was other feedback (and the moderation of your post had gone back down) I probably wouldn't have bothered.
The Radical Math example, while probably a real thing (and hilarious, from my point of view), showed no signs that it had ever been incorporated in any curriculum outside of avowedly leftist private settings, and had nothing to do with Common Core, other than an allegation that some people driving Radical Math were associated with some people involved with Common Core. This allegation included talking about how Obama is operating under Bill Ayers' agenda, which is a tired right-wing meme that I wish were truer than it is, leading me to discount the veracity of the entire account.
The second example seemed likely on its face to be an urban myth at best, and indeed I found no evidence that it's even real, far less associated with Common Core. It had the characteristics of an astroturfed internet meme (appeared verbatim across a swath of right wing blogs, referenced verbatim in comment sections of news articles).
To me, believing anything so obviously incredible indicates poor reasoning, regardless of whether you agree with the underlying criticism of the Core.
It seems likely to me that these kinds of stories are spread both by people who honestly if mistakenly believe them and by people who either willfully or professionally spread things they know aren't true for the purpose of promoting their viewpoint. Thus, idiots and shills.
I don't have a strong opinion on the Core. I don't have a knee-jerk reaction to the idea of national standards (if they're high). I'm a strong proponent of public education, I think that an educated citizenry is a vital national interest. I haven't studied the Core at any length, but what I've seen seems well enough thought out. I have no doubt that it will be implemented poorly in many places and outright stupidly in many places. Since the control is very local, I suspect that those places are probably making similarly poor or stupid decisions now. Fixing that is complicated and I certainly don't have answers.
Anyway, that's where I was coming from. I apologize for the personal attack. I usually avoid that, and should've in this case. The post pushed several buttons (bad evidence, organized propaganda/marketing, education) and I responded rashly.
