I find the guilt (I think that's the word I want to use) being manifested in this thread quite interesting.
The fact is that YOU get to choose how to feed your body. No one else. And, you can do it however you like. If you feel the need to answer to others b/c of your chosen diet, perhaps you should get to the reasons behind that. If you feel the need to convert others (or make a grande attempt at convincing them that your choice is, indeed, better and not really that hard to do), perhaps you should get to the reasons behind that.
Another person's eating habits are not of my concern. And, I eat meat.
