My husband is vegan and I am vegetarian, but my daughter is an omni. Granted, she doesn't buy her own food yet, so most of the food we bring into the house is vegetarian and a lot of it is vegan.
We still buy some meat products for my daughter. I didn't really care to do that, but hubby is the one that started it. We just don't really mind what other people eat, even if it is under our own roof.
When I first became veg, I really didn't like seeing others eat meat. Over the years, I've learned to relax about it, because no matter what, there's always the potential that I will be in a situation in which I'll see someone eat meat.
So yes, people can bring meat into our home, but I'd prefer that they have it already cooked as to not use our pots and pans to cook it.
