I've been thinking about this lately...when I met dh he was not veg...one night after he ate some meat, I could not physically bring myself to kiss him, even after he brushed his teeth... I don't think I pressured him or anything, just said 'I can't kiss you, you smell like meat'
He has not eaten cow or pig since, occaisonally fish (& then I really can't kiss him
We did separate for a month a couple years ago & told me that he ate a steak when we weren't together...i didn't think much of that at the time, but have been lately...I don't wanna have him be vegetarian b/c I am!
My kids are veg until they can understand what it means to eat meat. My 7 yo wanted to try his granddad's chicken in a restaurant & I asked him to remember where it came from, but that he could decide. He took a tiny taste & felt sad about it afterwards...but we talked about it objectively (hard for me!) and I didn't force him, but told him my facts...I don't think he'll want that taste ever again...but I didn't want to stifle curiosity, ykwim
My own reasons are: not wanting to impact the earth, walk lightly whenever possible...evolution has brought us to a point where we can survive WELL without consuming other animals--usually living longer & healthier lives...the meat industry has disgustingly low standards (ever read that krishna book where they quote gov't standards on the amt of chicken breast PUS allowed !!!

) and to devote my life to kindness, not murder.
Anyone else want to share philosophies? And how your family reacts?
