My condescending response started from:
LoL, believe whatever propaganda and rhetoric you want.
and
Now if you think you know better than doctors than go ahead and believe whatever the meat industry wants you to. I've done substantial research since then and my findings back up what I was told. I've now gone 13 years without meat and am doing just fine thank you.
I guess with the "lol" it's informative and useful, without, condescending.

Let me wave the white flag, since I thought I was responding accordingly to your post.
I'm not a fan of the way we do most things anymore. It's been quite a few years since I've really looked into my own diet, but the stuff I'd like to get rid of - primarily high-fructose corn syrup, added sugars or glutens or milk - is a royal pain.
Cucumbers are coated in wax, most plants have pesticides unless you want to try organic which cost much more than non-organic. Tomatoes are picked under-ripe and gassed to ripen just before being sold. I'm really uncomfortable with irradiating any foods. Unfortunately, there isn't enough room in my backyard to grow all the vegetables I eat, so I know no matter what I do, there is always something wrong with it.
