Thanksgiving Family Drama

I am aruging with my aunt over text message. I wish she would justI don't want to start a fight or anything. I am personally animal-creulty free on all accounts because technology has surpassed the days of animal testing with a machine that saves money, saves time, is more accurate, and shows long term effects. With devices like this in the medical field we would help more people far more effectively. We have cured cancer in rats for decades. Maybe with this, we will find the cure in humans. As for makeup I see it as very cruel to harm animals for superfical purposes, but that is just me. She says that she will loose her job if I had it my way to start animal testing all together but to me ethics are far more important. It is a cause bigger than any one person. Now I am no longer allowed to speak to her or her children. The thing is, she started this whole arguement as she always does. Every Thanksgiving she picks a fight with someone. First it is with my father, because she is Catholic and he is a Muslim. Then my mother for having  better curves than her. Then her own husband because when he was 18 he and his former girlfriend had an abortion. Why does she always have to be so attention seeking and rude to literally everyone? Soon no one will spend thanksgiving with her (which is what I am doing now) and she will complain about being all alone when it is her fault. 
Who is wrong here?
Update: this was brought up because she asked why I never wear the Mac pallet she got me a few years ago and I don't lie so I didn't sugarcoat it for her.
