I think Suffolk is right, food, sex and religion are great ways of controlling others.
A friend of ours, while serving us a bake of vegetables and minced meat topped with real cheese

, started to pointificate on the evil of milk products for one's health and so on. I kept my mouth shut and enjoyed the meal. If milk is bad for me, so be it, I don't smoke, drink very little and work out, so I must die of something. Milk, for me, is worth it.
Anyway, she had oats milk and almond milk in the fridge and offered us some (tried both before, but don't see the need for me) and while Axel pointed out, what large style almond farming in the US (where most almonds are produced) does to the enviroment, I tried to get the whole thing back to a slightly less serious tone and asked her how she could drink horses out of their main food source (I know, I know, it isn't true, but I thought it would be ridiculous enough to be seen as a joke). It didn't work, she was in crusade mode.
The really important thing is to look at all our food choices and try and work out how they impact on the environment and everything else. Oats, in Europe, should be fine, as they grow well here without too much intervention. Almonds in California use up more water than the area has to offer, so, for me, almond products should not make up a large part of my diet (I still bake with them, but that makes a few packets a year).
I do eat meat, but try to buy local organic when I can afford it. More difficult with fish.
Just a few random thoughts from an omnivore who does not eat meat every day, but loves her milk.
