"Vegetarianism is crueler than meat-eating." The typical meat-eater also eats eggs, honey, dairy cheese, drinks dairy milk, wears leather. It's true that many vegetarians eat a lot of dairy cheese. I'm not sure how to measure the cruelty necessary for feeding a typical vegetarian and a typical meat eater, and then to compare the two, though. What does that math look like?
"Vegetarians wear leather, silk, and wool." Some do, some don't. I would assume those vegetarians who are motivated by compassion towards animals would attempt to avoid these products. I know I did, back in the day.
I realize there is a limit to how much info can be put into a 5-minute video, but the thing is, vegetarians are a more heterogeneous group than you give them credit for here.
I also think a lot of the people who are currently vegetarian could have been vegan if society was more accommodating and accepting. Being / becoming vegan is unfortunately not nearly as easy for everyone as we would like it to be, or as easy as PETA and some other advocates portray it. Some people try and fail. A lot of the failed vegans go back to meat eating. Some go back to a flavour of vegetarianism. AFAIK the percentage of the population who are vegetarians & vegans has not increased much over the last decades, even though we know a lot of people try going vegan or vegetarian. That seems to indicate that there is a steady stream of failed veg*ns who revert to omnivorism. Which again is evidence that it's hard for people to stick with it. Even vegetarianism, apparently. Which again is part of the motivation for boards like VV.
