I concur. It bothers me that at the top of part 4 she says she regrets having decided to become a vegan through being swayed by graphic images of factory farms rather than having "adhered to the rigorous academic standards" that she claims to use in all other decisions -- and yet this anecdote turned polemic will surely be used by others in hastily making up their minds that veganism and possibly vegetarianism are not viable or beneficial to either the individual or society.
