Thinking back, it seems to me that some people here were genuinely offended by the site. Just out of curiosity, what has the creator of it done to earn anything more than a good laugh and dismissal?
Looking at it, I can only wonder how serious the real creator could be; there are a few aspects of it that suggest it was created as a joke, such as what appears to be a conscious effort to make the site as cheesy, blatantly stereotypical, and unprofessional as possible. Unfortunately, if it is a spoof, the author is talented enough not to give any explicit tip off (as far as I have read), perhaps with the exception of the cute picture on the main page.
The people who would be interested in the site are primarily those who have mindsets that are already dead set either against the position it states; people who are more ambivalent on the issue are much less likely to care about the site, and that is providing they managed to find it in the first place, since it's not generally accessible on the web but is, rather, distributed almost exclusively between within one of the opposing groups (think about how you discovered the site).
Either way, I say that there is really nothing to fear from old Jerry here, and it's probably not worth getting too hot and bothered about.
Anyway, that's just something I've been thinking about.
