The extreme heat that such a mild-mannered, calmly reasoned column has generated is a sign that McLaren has touched a nerve. 

I tried through my thirties and forties to ignore the truth about all this too, but finally came to realize, just as she has done, that the reasoned arguments really are all on one side of this argument: giving up (or at least radically cutting back on) one's consumption of animal products is the best thing for the environment and for your own health--as well as for our fellow creatures.
