Fois Gras is just an example. It might be a Buddhist and someone who goes shooting or fox hunting. Do Buddhists view that person in exactly the same way as they do anyone else? Or do they have repulsion towards their activities and so therefore avoid association or friendship with them? What would the Dalai Lama say?
It is always a difficult one with regards to assosiating with people who's views I find abhorant. In an ideal world all fox hunters are brain dead morons but people often aren't as one sided as that.
