I have 2 arguments for it:
1. Food flavor
2. Energy level
I took a raw cooking class last year & it was some of the most delicious, best-tasting food I've EVER had in my life. I appreciate food, and it was just great! Plus you hardly need anything to "cook" - a blender, a food processor, and a dehydrator is pretty much it. I eat a Vegan restaurants every chance I get because I always discover new foods or different combinations of flavors that I don't find in traditional meals (especially given my food allergies). Some of the Vegan food I've had has been absolutely off-the-hook, which I never realized could happen without meat simply because I hadn't been exposed to it. Plus you probably already eat a lot of the stuff...bean burritos, oatmeal, a lot of Mexican food, bean chili, etc.
The second thing is energy level. When I've gone on a full-Vegan diet (not junk-food vegan, i.e. Boca burgers & soy ice cream), I've felt fantastic. I do road biking & I can do a 30-mile loop without even feeling tired at the end. So having constant, 100% energy all day is a HUGE benefit. The downsides are that it can get expensive (lots of fresh stuff) and you basically have to cook every single thing you eat, which is time consuming (both to shop & to cook). Plus, I love meat, so it's hard to give that up! The only downside is when you lose Vegan edge:

Here's the problem I have with the Vegan
Industry and, more insidiously, the raw food
Industry.
This is one of those diets and more appropriately, lifestyles, that is not inherently bad. Indeed, there is a lot of sound truth to these diets that are very beneficial. However, like with any of the community-based diet movements tied in large part to what should only be called Nutrition "science," they are forever tainted by being driven by marketing and ad sales; never by real science. Don't ever, ever trust the majority of "data" published through any of these trade-driven markets.
And, this is the sad thing. What should be seen as one of the most important sciences in terms of directly impacting human health and lifestyle, the Nutrition field, is purely dominated by snake oil salesmen. To me, it is impossible to differntiate the Raw foodie charlatans claiming hogwash such as: blending your walnuts will cut the vitamins to pieces! or, humans did not evolve to eat meat! (the biggest lie to come from these knowledge-bereft huksters). The research is generated by industry, not by science.
Don't tell me things like "energy quotient" or "vitamin loading" or "juice cramming" because they are meaningless buzzwords that provide no value beyond the self-aggrandizing industry that coins them.
Now, is it a good thing to go after the industrialized meat industry that shits out high quantities of overly-processed goods, encourages us to eat more and more of it for each successive generation? Yes, that is a noble cause. Just don't pretend that the ones most actively championing such causes are actually providing you a better alternative (meaning--an alternative that is not driven purely by profit).
We very publicly damned the tobacco industry, and ourselves, for having allowed them to provide the only serviceable data regarding nicotine for decades. It baffles me that this model exists today with the "organic" industry, which is largely owned by Dole. That, and the neohispter shaman monks that tell me that I should be bathing with stones and eating raw food, based on their own wood spirit telling them that this is so.
No...just, no.
