Why? I am asking because I follow Buddhism but wanted to know how to view things that conflict. Buddhists are supposed to forgive, but do they still exercise their right to not be friendly due to something they disagree with?
If one has got a problem with eating fois gras, one should also have an issue with anyone who eats any 'living life'.
Just because one is of cruety does not make it less of an 'evil' as other form of killing and eating.
As long as the concious is clear of the deed, and you can balance your guilt and your believe, then it can be forgiven. There are plenty of other mantra that states do no harm, but you also get Tibetian monks kicking the living lights out of others, because they balance their guilt to their perceived beliefs.
At the end of the day, I'm only a Taoist / Buddhist. I don't follow the full mantra of 'do not kill life', not the murderous bit, but the consumption of animals. I am not against fois gras either.
It's all down to you and how you believe the teaching is telling you. Easily twisted for evil but then, why follow it if evil is what you ultimately want to follow?
My last lesson with a buddist monk was about 14 years ago, so a little sketchy on the teaching and advise we got when we questioned similar stuff - especially about the eat and killing of animals.
