Most people do stuff like this to sharpen their teeth.

There's a great recording on Youtube of a biology grad student debating Kent Hovind on the broad subject of evolution. Even though Hovind is essentially a confidence man, the conversation is enlightening nonetheless because the grad student knows his shit and gives some surprising lucid explanations that I haven't heard in other general audience discussions of evolution.

Also, most people rely on a kind of "smell test" to keep from engaging with certain types of arguments. That can quickly create a moral hazard where the person being avoided misrepresents people's reluctance to engage as proof that he/she is a noble dissident with the courage to speak the truth.

When someone like Chomsky, Ken Miller, Glenn Greenwald, or another intellectual engages directly with such people it pushes them into a corner where they either have to deliver the goods, change the subject, or commit a fallacy.

In a debate, Greenwald forced one of the former NSA directors into such a situation when the response was, "Collect everything doesn't really mean collect everything." Trusting nature of most people being what it is, these forced errors have value.
