I respect the choices of all people, when it comes to their diet (except perhaps those extremists that choose to eat live animals). Nonetheless the article comes off as apologetic towards meat-eaters, like "Hey...yeah, I eat only veggies sometimes, but I still have my pastrami on the side...so I'm not one of those extreme weird-o vegetarians, or worse Vegans." Of course, the author didn't say this...it's just how it came across to me.
I was vegan for 5 years, and have been vegetarian for the last two. I eat cheese now, not every day though (I treat it more like a treat to be added lightly than an essential), and I still don't purchase cow's milk, preferring the almond/rice/hemp/coconut varieties. Nonetheless, since I am unimposing when it comes to my dietary choices, I've hardly scared people away. In fact, even though when asked I am unapologetic in my reasoning, I've managed to get a couple friends to consume less meat,and my household to become semi-vegetarians that consume meat mostly when they go out.
Treat people with respect, and they will respect you and your choices.
