Ridiculing cable believers is the same as engaging in racist humor? Perhaps we need to create a new protected class for our civil rights laws? But ignorance, unlike race, ethnicity, gender etc., is not an immutable characteristic.
Furthermore, my real point, I guess, is that it's sort of strange for people to come onto to this site and start posts with the express purpose of making fun of most or many of the people who started and now participate heavily on this forum. Imagine someone starting a thread on a wine taster's forum about how stupid it is that people spend a lot of money on good wine.
Look, I can take a joke as much as the next guy, and I don't want to extend my point too far. This really isn't that big a deal. I just think it's interesting that a certain subset of the "objectivists" on this forum are not content to engage in a dialogue about the substantive issues that underly this thread, but seem compelled to insult and make fun of others. I suspect most of these folks are a little immature or insecure (a characteristic that is arguably evidenced by your "ignorance" comment).
