there are endless amounts of these people on youtube, and a lot of what they're saying is badly researched and scientifically inaccurate. they seem hellbent on shaming people who have either no desire to start with, or have 'turned their backs on' veganism. probably giving vegans a bad name.

stuff like this is funny to watch though
