One interesting thing I'm discovering is that vegans are just as prone as anyone else to spread misinformation (of all sorts). When a product or menu item is identified as "vegan" online (by any source, it seems), that info spreads like wildfire - whether it's true or not. I'm finding myself not trusting most sources online, with the exception of a few bloggers and industry folks, and the manufacturers/restaurants themselves.
There's also still a huge problem in a lot of vegan chatter about "true vegans", which usually involves name calling, love/hatred of PETA, discussion of honey, and value judgments about health. Mention Oreos and Ritz crackers as being vegan some time to a group of 'em, and you'll see what I mean.
All that said, I'm still diggin' it. I've made very successful vegan blueberry muffins, very unsuccessful brownies, and our homemade seitan is surprisingly tasty.Still looking forward to the next few weeks, too.
