People Speaking - Shrug

All by my father (see also here).

— "Of course there are millions of people who don't eat meat. Even billions. They are the niggers in Africa. That's why they are underdeveloped."

— "Ever since you told me you're vegetarian I don't live. I just exist. I can't eat meat because I think about it. I can't eat vegetables either because I think about it. I can't drive because I think about it. I can't work because I think about it. But it's alright, because in the end I will die a physical death. It's you I'm worried about. But you seem to care more about a cow than about me."

— "... Of course I can just avoid talking about you at work. I have a friend at work who has a daughter and he never talks about her, because she's mentally ill. For example she doesn't eat anything that wasn't prepared at home. I told him once - 'At the cafeteria they are giving away untouched prepared packed meals, why don't you take some home?' He told me that he would, but his daughter wouldn't eat it. So it's possible that I just won't talk about you either."

— "It's all an idea. And all ideas are bad. I would understand if it was for health, but you are avoiding meat for an ideology and it's just inconceivable. About other people I can shrug, but about my son I just can't remain indifferent. I can't support it in any way."

Now suppose i win in these arguments. How can i win them without humiliating my father on the way?
