Don't cite the crusades and make me sound like the Roman Catholic Church. I too enjoy science, and the scientific method. In fact, as an animal science major, that's what I do, all day, everyday.
This site is full of two things: opinions and facts. If you want to check the factual basis of opinions, be my guest. I just found it random that you pull the topic of spinach in diets out of nowhere, insist that the fact is wrong-- find out it's right, and yet, you're the enlightened one? I don't need to cite my sources, no one here does, we all simply share our experiences and what's worked for us. If you want scientific evidence go ahead and do a literature search, but it's insulting to others to imply that they are ignorant simply because they haven't backed up their thoughts as you would like them to. This isn't a scientific symposium, it's a turtle chat.
And yes, that gravel must go. Although, I do enjoy the rest of the set-up, it;s very modern.
I understand the excitement in posing an academic challenge. But, as is always the case with the internet, wording is everything. 
Excitement can easily be misread as an accusation, criticism, or even a threat.
are a wonderful way of making sure what you write does not get taken the wrong way.

. Discussions like this motivate us dig deeper for the facts. It also moves the old-timers to expound on the reasons once again (sometimes to their frustration). It's all good though, IMO.
