Good point. I would also not accept her using a reference to FR (unless the topic was FR), but I do find this site a good source for locating more primary sources to quote from, just as you have said.
Having said that, Wiki is not a good source for factual information on political, religious or historical information that is subject to debate by conservatives. But it remains a starting point for other issues or to beging researching a subject one is not familiar with.
Because it is a compromised source I tend to steer her away from Wikipedia, but if she used it to help her locate other sources I probably wouldn't stop her, but I would use it as an opportunity to discuss the inherent risks involved with using a known tainted source as a beginning point for any study.
Right now I have her studying logic, fallacies and soon to include information on debate as part of her social studies. I want her to be equipped to see the holes in arguments.
I remember a college course I had where I compared the same story in Time versus Newsweek. I was amazed at the difference between the two. Same story yet totally different perspective. I then compared it to US News & World Report and found a third difference. That was my initiation into political and PC bias in reporting and I’ve never forgotten it.
I also remember a funny story about Bill Clinton cheating at golf when he was in Australia. Reported there but ignored in the US. I’m sure your daughter will find lots of things just as interesting that prove the bias issue.
