Bolivian farmers don't think, feel, or suffer? Quinoa is the most exploitative food products you can imagine. I'm aware the iPhone play is a cop out, I'm working or I'd type up a better argument. I'm not trying to convince anyone to not be a vegan, I fully support people finding any way to reduce the harm they cause to the environment, to a point. The zealotry associated with veganism is the only issue I take with it.
I'm not vegan, but pescatarian. I'm aware my opinion on vegans is fully skewed by my interactions with a few, and projecting it on every vegan is problematic. That's kinda the point I'm trying to make, though, some vegans do much the same, but to everyone who isn't vegan.
