Hmm, I don't wish to belittle anyone's choice in reading material or the products which are being promoted on this website but aren't titles like
Why Evolution is Stupid immature and unprofessional? I don't like President George W. Bush but if I wanted to write a novel detailing the reasons why I would surely think up a better name than
Why the President is Poopoo.

Heh, seriously. In fact, if I were writing such a novel I'm sure that my editors and/or publishers would at some point suggest I use a more appropriate, mature title. Especially if I want to convince my audience!
If I'm interested in disproving an idea I'll make great pains so as not to come across as emotional or that I'm simply writing an angry diatribe. Instead, I'll reinforce and strengthen my argument with the most mature angle I can adopt.
What's more, can you imagine the heinous offense people would take to a title such as "Why God is stupid". And maybe there is a book out there with such a title or a similar one, but I wouldn't hold my breath that it's a well-written piece of work.
It'd be interesting to see what this video has to say and if its content is better thought up than its title. I'm sorry to offend anyone's interests here but a name like that really does stick out.
